mpg plays badly in divx dvd player

[ssalim]

Hi, I have two .mpg files, both converted from dvd using vob2mpg
001.mpg plays well on my philips dvd player with usb 2.0 divx playback
however 002.mpg does not. 002 seems to stutter every single second.

GSpot info on those: on those:
Both: 29.97 frames/sec
Both: 720x480 MPEG-2
Both: audio AC3 48KHz

001: 55,80 frms, 4998 kbps, 0.483 Qf (len is 31 minutes) -- audio is 256 kbps
002: 105,07 frms, 7518 kbps, 0.726 Qf (len is 58 minutes) -- audio is 384 kbps

What should I do with 002?

Thanks!

I guess it plays fine on your computer?
Are you playing from cd,dvd media? or through the usb-port?

You can try "fix" the mpg using videoredo (quickstream fix) and see if it plays better.

[jman98]

The video bit rate in file 002 is relatively high for DVD, although certainly well within the specs and not even close to being too high. But you are trying to play it this back apparently in file play mode and not as a DVD. Maybe your player doesn't like the bit rate that high in file play mode. I wouldn't count that out.

[ssalim]

I try to play them through the USB port via external hard drive (western digital elements 640gb fat32 file system) (apparently it only supports fat32).

Edit: yes they all play fine from my computer. Maybe I should just get a media streamer from pc to tv but that's not wife-friendly .-friendly

Its the philips hat will only recognize fat32 partitions...you could also try defragging your disk.. as, if this is a download from multiple sources, bittorrent? then it will be highly fragmented. Your philips (???) may only have a USb1.1 port thus your second file is easily going to overwhelm this, on the bitrate spikes . Try remuxing the second file with 128k mp3 audio and see if it plays any better.

Wd Tv is simple, easy to use and small...

[jagabo]

Which Philips player do you have?

That was kind of important to know. You should have said so from the beginning. The less you tell us about what you are doing, the harder it is to get you helped.

See RabidDog's post. It could be a high bit rate issue via USB.

I did say "on my philips dvd player with usb 2.0 divx playback" I thought it would be clear that I was using the USB port not the dvd tray.
The 001.mpg file is from a physical dvd disc to computer internal hard drive using dvd decrypter then to .mpg file using vob2mpg... not bittorent or anything from multiple sources.
However, 002.mpg is from sony camcorder > finalize > dvd decrypter > vob2mpg

I have phillips dvp5982.

Any solid program for "remux"? I'm so clueless...

What is "Wd tv" I guess I'll google that, too.

Thanks.

Edit: About the "Wd TV", it seems nice but I already purchased this dvd player and the external hard drive...
Wow it supports NFTS and loads of video "MPEG 1/2/4, WMV9, AVI (MPEG4. Xvid. AVC). H.264, MKV. MOV (MPEG4. H.264)" ... this dvd player does not support H.264 and MKV and maybe others... darn it's $100.

[jagabo]

The Philips 5982 does not have a USB 2.0 port. It's USB 1.1. You can't play high bitrate material off it.

The 5982 doesn't seem to be listed at Philips' web site anymore but I remember it used to say something like "compatible with USB 2.0 devices". There was a long discussion here and it was eventually determined this simply meant it had a USB 1.1 port and you could plug USB 2.0 devices into it. Of course, the transport rate remained at 1.1 levels. You need to move up to the 5990 or 5992 to get a USB 2.0 port that can play high bitrate material.

[ssalim]

*curse* I'll try to return this junk then.

So would you go for the newer version or WD tv?

[jagabo]

The WD TV is a better deal but it doesn't play DVDs.

[ssalim]

It does not... dang of course it does not. I saw RCA connection but it's the output, not input. Well then my options are remux many videos, live with 5982 or buy newer version... anyone recommend a great brand and model of dvd player with usb playback? Thanks.

Edit: interestingly, this website says it does have 2.0 USB

Maybe it's just USB2.0 supported but it's actually 1.1, like you mentioned.

[jagabo]

Remuxing won't help. The high bitrate of the video is the problem.

The aforementioned 5990/92 are among the best Divx certified DVD players. They do have USB 2.0 ports and can play high bitrate MPG files via the port. I bought one several months ago from Walmart for about $55. They are hard to find now though.

[ssalim]

There are refurb ones on eBay for $53-ish... but it's refurb.
I can't find them on walmart (online)... maybe local?

Sigh.

[jagabo]

Buy.com had refurbs for $35 a few weeks ago.

[ssalim]

Does the 5990/92 play more formats (like MKV and H.264 etc) or same as 5982?

So there is NO way to reduce the bitrate of the video?

[citanool]

It does not... dang of course it does not. I saw RCA connection but it's the output, not input.

What difference would RCA input make ?

You could re-encode of course, or just burn original file to DVD as data.

[ssalim]

I'm confused with "just burn original file to DVD as data."
Can you explain?

[jagabo]

Burn a data dvd with the MPG file on it. Just like you would with any other data files. I use Nero Burning ROM and make ISO/UDF discs.

[jman98]

I did say "on my philips dvd player with usb 2.0 divx playback" I thought it would be clear that I was using the USB port not the dvd tray.

Fair enough, but that statement is ambiguous and it could simply mean that the DVD player has USB 2.0 playback. Your statement as written does not explicitly state that you used such. If you had said "via USB 2.0 playback" it would not have been ambiguous, or you could simply have rewritten it to say first that you used USB 2.0 playback on a Philips DVD player instead of leaving it ambiguous as to whether the USB 2.0 statement modified the player or described the method of playback.

The WDTV player can play DVDs, but not directly. They must be ripped or in ISO mode. I find it subpar for DVD playback, but it's great for other things.

You can count on one hand the number of DVD players that currently support MKV and H.264. I know of exactly 2, although there may be a few others I don't know about. Devices that can support MKV and H.264 can easily be found, but they are not DVD players. They are media players and/or media streaming players.

Yes, you can lower the bit rate of your file, but you'll have to re-encode it.

[ssalim]

Good to hear, what software would you use?

[RabidDog]

I have gone from 5982 usb1.1 port to the WDTV and it is better.. I am still resolutely SD but the WDTV has exceeded my expectations.. its not perfect by any means..but it offers a better playback experience. the remote is small but usable and the picture output quality (even over composite!) is very good. Long filenames, lots of space, quick boot up and Toslink slot nicely into my video ecosystem..possible network ability in the future..
All that and Cornbeef sandwiches, Grommit

[jagabo]

I would use VirtualDubMod and encode with Xvid to keep bitrates below 3000 kbps in a from that the 5982 can play (Xvid AVI). Or AviSynth and VirtualDud, and Xvid. If you want something more automated you can try Super or AutoGK.

[ssalim]

Ok I'll try that jagabo. That's the cheapest solution ($0).
The best one is getting Wd TV and keeping this one for dvd playback only, but that's $100.

[ssalim]

I re-encoded one with divx 1-pass with 3000 bitrate (I'm no expert) and waited 1 hour (not literally waited in front of monitor) and the result is great. It still stutters but it's watchable. I'm going to try 2750 bitrate, what do you think?

[jagabo]

It shouldn't stutter at all. I would try using single pass target quantizer with a quantizer of 3. That does run a risk of the bitrate exceeding 3000 occasionally but with DVD sources it's very infrequent. If you're using b-frames try using 1 instead of 2.

Are you using the original frame size (720x480) and PAR/DAR flags? Or are you resizing to square pixel frame sizes (like 640x480 for 4:3, 640x368 for 16:9)?
