HDTV Tuner & Capture

Chakotay2 · Member Joined: 07 Aug 2001

I want to aquire a HDTV Tuner/Capture card before the July 1, 2005 broadcast flag deadline.

Ultimately I would like to have it work with services like titantv.com and be able to burn to a DVD.

I am a total newbie at this but two cards have been suggested:
MyHD MDR-130 or the Fustion HDTV card.

Can anyone help? I have searched on the internet for recommendations and I trust the people here to give me good info.

Thanks in advance for excusing the "newbie" in me.

Also, it may be helpful for you to know I live in the USA and receive terrestrial HDTV from an antenna.

All the current cards are for over the air DTV(USA), DVB(Euro) capture only. The hardware and apps currently do not support import from cable or sat tuners or DVD burning except as data (long winded technical reasons). Currently doing more than this is highly specialized.

Don't buy anything unless you want DTV over the air solution only. No hurry.

I have a MDP 100 and have used it for almost 2 years now and can report back my experience with it.

As far as PC HDTV goes it is an excellent capture card. I use it with a 2.5Ghz p4. It can be taxing on the CPU (min spec is 800Mhz) when tuning a digital channel but not during playback unless a drop out occurs. Higher speed CPU will be able to lock and re-sync a weak station (below 60% signal) without issue, slower CPU will need a stronger feed. Shows just how poor the VOOM reciever I have is

This card will also only work with OTA and accepts any analog feed. The fusion card is the only one that will do QAM decoding (digital cable - non encrypted).

The HDTV tuner card is not compatible with other capture software (must use theirs). Compatibility problem is with digitial tuning lockups, had mixed success as using it on analog stations this way. Software supplied with the MDP works well in its latest version, interfaces with Titan TV, supports a remote, and can capture using any installed codec. Also the timeshifting beta drivers work flawlessly on my system, can play back DVD (AnyDVD to get around CSS), and has full controll on the output format for scaling to another device.

Don't expect support from Windows Media Center anytime soon (2005 is a bust for HDTV). Most other forms of HTPC solutions suffer from using the MyHD software as the tuner, maybe someone else has had good success.

Capturing HDTV directly as a TS stream (no compression) is great. I do compression after capture and save DIVX files on my drive. Have taken some shows to DVD but you do have to re-compress the video and scale it to 720 x 480.

I get to AVI or DVD by using HDTV2MPEG2 to cut out commercials and save off an edited transport stream. Then I use Canopus Express to go directly to a DVD compatible MPEG2 (DVD Lab to author and write it). Canopus supports DIVX and WM9 as well and I have been successfull with direct encodes using DrDIVX off the TS. I have struggled with other methods but always had issues with audio/video sync in the final coded file.

Only a beginner when it comes to video conversion so these tools work well for me.

TS streams are highly compressed -- but otherwise thanks for the very informative post

So it sounds like after capturing with an HDTV card it is somewhat difficult to burn to DVD? Is that assumption correct?

Looks like this converter will do the HDTV TS to normal DVD MPeg2 downconversion.

Great! Now to decide which video card will work best. From what I am hearing the MYHD card's are pretty good.

Unless I hear something else, looks like I will be headed that direction.

most encoders like procoder, main concept and vegas will do the conversion -- all will take TS files native

How about programs like NERO? It will usually recode other files to burn to DVD... Will it handle HDTV Captures?

Great! Now...which card...which card will it be? Any ideas?

I have the DVICO FusionTV3 HDTV tuner card. Haven't really used it that much. We only have 4 local HDTV stations around here and I just have an inside antenna. Unfortunately the only station that transmits true HDTV broadcast is the public TV station and I haven't seen anything I would want to cap.

I output HDTV through a Sapphire Radeon 9550 video card to my projection TV. I use a ATI DVI- Component converter. Great quality with a good HDTV signal. The card comes with software to convert the .TS file to MPEG video. The card also receives the regular or cable channels, but I would have to change antenna connections for the cable. (Not HDTV cable)

The card is cheap enough, about $150US. I don't know that I could for sure recommend it, because I haven't tried any other similar card.

I use the ATI component converter a lot more. Anything I can play on the computer I can output to the projection screen with good quality.

HDTVtoMPEG cannot produce a compliant mpeg2 file. The option is there but it never worked (file is corrupted). Stick with transport stream output.

The TS stream uses AC3 sound, which means Vegas cannot import it as there is no support for AC3 in that tool. DVD architect will take the sound as an import so you could go an all Sony Vegas route. It's cumbersome and the sound can get out of sync (can be fixed). Too rich for me to be that much trouble so don't go that route. I trialed it and still prefer the Canopus coder.

Premiere can be used to if you have the right plugins but you have to resize before you import the video else it will not accept it. AVISynth scripts are the way to go this route. Anytime you demux the streams, going to be fighting audio / video sync. Can be done but it is a hassle.

Check out the AVS forums for information on the Fusion QAM. The card cannot read an encrypted feed so if you cable company does this, you have to use their box.

My path does 1 downconversion. HDTV2MPEG2 only clips out commercials or unwanted video (does not re-code). Canopus Express does the recoding to DVD MPEG2, and DVDLab composes the vobs for burning. The quality on my projector is better than than the Series CD's I have bought but I find their encodings are usually poor and I keep my bitrates high. YMMV.

I try not to downconvert HDTV to DVD at all? The future is HDTV, so for now I save all my HDTV programs on multiple DVDs. When the HDTV DVD war is finished, I'll transfer the programs to the wining format

and never have downconverted to SD.

But for those rare occasions when you must convert to SD DVD, HDTV to DVD conversions can rival commercial DVD quality, depending on your local station's compression hardware, and your MPEG-2 encoding.

Unfortunately, there isn't a simple way to convert yet, but here's what I do:

1. Use DGIndex (from http://neuron2.net/fixd2v/decodefix.html) to create a D2V file and extract the AC3.
2. Use an AVISynth script to convert and scale the video to DVD standard:
a. For telecined 1080i, use:

There is a real simple way to convert:

Canopus Procoder Express
or
Canopus Procoder 2

Directly from stream to DVD, can edit out comercials in that tool but I still prefer to use HDTV2MPEG2, works well and supports AC3. I did used to use the demux, script, Vdub method...but so much easier now.

Has anyone captured from the D-VHS type stream coming out of the latest HDTV cable boxes (Motorola 6xxx and Scientific Atlanta 8xxx) over IEEE-1394?

Very informative thread.. thanks! Couple of questions.. So..

The ONLY way to record/capture non-OTA HDTV is via a HD-compatible PVR, correct (b/c of encryption)? I have a ReplayTV, but no HD-compatibility. Could I upgrade my Comcast box to it new HD PVR, then xfr to my computer and downconvert to DVD or simply span across mulitple DVD's? Or is the video stream permanently encrypted?

Xesdeeni, just curious, for a ~2 hours of HD video, how many DVD-R's do you need to span across?

Rynoc, is their a detailed guide to your 'simple' downconversion method from HD to DVD using HDTV2MPEG2 and Canopus Procoder Express or CP2?? You could just as well use Cinema Craft Basic, yes?

The TS stream I have from the MyHD card will not load into CCE Basic directly. At least not the version I tried late last year, I have read some have done this with streams saved by other capture cards. I could convert it into something that CCE would recognize but by then I could have gone to just about any other encoder.

Never had a guide for procoder but it is easy to learn and use. Too bad they don't have real demos other than the 1.25 version you can get by registering on their site. Thier target is business more than consumer.

I'm on VOOM for satellite so no options to go from HDTV to PC yet (closed system - DVI-I output or composite). Hoping if they launch PVR in March something may be possible but doubt it.

I'ts all a question of storage capacity. For me, convert to HD Divx (1/5 th the original stream size) with no discernable loss on a 9' x 7' projector screen. Can get almost 3 hours on a DVD-R that way and enough on a couple of hard drives to have a decent media collection.

Space is not unlimited for me and I am willing to loose some quality for ease of use. I may start compressing more in the future.

I tried hooking up Samsung SIR-T165 and Panasonic TU-DST51A set-top boxes to my computer via IEEE 1394 a year ago, but the computer couldn't detect any type of connection. I thought it was impossible, but doesn't that new Sony 1080i camcorder record on MiniDV tapes? I assume there's some way to get that 1080i stream onto a computer. Maybe the same method can be used for D-VHS or HDTV set-top box capturing.

Also, I recall (a while back) someone saying that the first JVC D-VHS recorders could record off their HD component video inputs. They stopped producing them though because of copyright issues.
