MPEG2 files can play on most DVD's , yea?

[squadjot]

Hey, i need ur help again ..

My task is to create a DVD that should lpay some trailers continuesly, i'm not the big DVD authorer :P .. and i dont have a fancy DVD menu/authoring program..

I was wondering if i could get around with it easy by simply using mpeg2 format, doesent that play natively on almost all DVD players?

any other suggestions?..

if i can go for MPEG2 (and then burn it as data file).. in what area should my bitrates be? (my guess is around 6000-8000 kb ? yes?

any help , pointers would be great

Most DVD players require that the MPG2 be "authored" into the appropriate format (VOB) and structure (VIDEO_TS with the requisite ".IFO", etc.).

I'm not familiar with the apps on PCs; I'm sure there are some authoring apps that will take your source video (which is what format?) and convert/author it for you. As well, I'm sure that there are some free apps.

Be patient; some folks will chime in very soon with what you need.

No, you must author it as dvd-video if you want it to play on almost all dvd players. It's most DivX DVD players that supports mpeg1,mpeg2 files burnt as data.

oh..ok..so.. now i'm this far: i have now a bunch of .IFO, .VOB, .BUP files.. whats next?

If they are DVD compliant, complete, and in a VIDEO_TS folder, just burn them. I use ImgBurn for that. Select the 'Build' mode, then burn them to a DVD.

Ok, i suceeded burning a "miniDVD" with nero 7.5, i now have one last issue.

The Video was choppy..like it could not pull the bitrate. What bitrate should i use for this?.. the output is 720x576 PAL

Let me guess, you're saying "MiniDVD" because you burnt the DVD material onto a CD-R right?

That's probably your problem, because even though your player can recognize and read the disc (which is better than most AFA MiniDVD/DVDonCD), your player's drive isn't built to spin CD's at a fast enough speed to give you the bitrate it needs to output smoothly. Sure, DVD's can do that, but their spec is such that the output from them is ~9x a similarly spinning CD would give. Basically a throughput bottleneck at the playback source...

Solution:

Try either 1) re-encoding at a lower bitrate (~2500kbps?) to accommodate the CD-capable speeds, or 2) burn to DVD-R instead. <or 3) live with it being choppy on YOUR player, but ok on some others>

Cornucopia> thanks alot.

a bit off, my DVD recorder wont burn , when i try to burn a dvd, in NERO it gives me the error, "power calibration test failed" ... hmm..

Use Imgburn 2 to burn, instead of Nero, and see what happens.

What media are you using ?

[Cornucopia]

*Funny thing is, (only) recently I've had a number of discs that when burned in ImgBurn exhibit stuttering, while same discs burning same folders/image don't stutter after burning with Nero. Maybe there's additional influences going on here as well.

Curious. I haven't had any problems with discs burned with Imgburn 2.2 across several machines and playback devices. I can't compare to Nero as I uninstalled it after Nero 6, and haven't been back.

[redwudz]

Power calibration errors usually mean a media problem. The burner needs to write to a calibration area near the center of the disc on each burn to set the laser power levels. If if fails to write or read correctly from that area, you get a PCE. Other problems that can occasionally cause it are dirty laser lens or a failing laser. But media is cheaper and easier to change.

[squadjot]

ah..thanks for your reply's ..you guys are great.

I'll try and fiddle a bit..get some clean fresh DVD media's, and maybe try that Imgburn 2.2 aswell, thanks

Any DVD player that supports Divx will most likely be able to play what we call "raw" MPEG files. These are unauthored MPEG files. I've burned a bunch of VCD compatible files to DVD+R as files on a data disc and they play fine on my DVD player, which does support Divx.

Gotta love Nero. The "Power calibration test" error is nonsense. Basically it means that you are burning at a speed that the writer doesn't like. The fix is either to set Nero to burn at the maximum speed (I mean to use the setting called "maximum") or to burn at a slower speed than you used, but I don't remember which one. Sorry, but it is one of those 2 choices.

miniDVD actually can take bit rates up to about 4400, but not much more, assuming your DVD player can even play the discs. Anything above about 4400 Kbps requires the disc to spin faster than the drive will do. Firmware prevents the drives from spinning more than something like 2X speed for CD-Rs because none of the formats commonly on CD discs (data, VCD and CD audio) require speeds above 1X and spinning at only 1x or 2x prolongs the life of the drive.

jman98 > alot of usefull information, thanks alot!!
