confused with divx files that work

[ceve4life]

I have recently been trying to play files on a dvd data disc that are all divx but not all of them will play on my dvd player. I've checked all the properties and they are all avi./MPEG Layer-3/compression Divx, but only some of them will play. I didn't format any of these files myself, they came that way so I figured it wouldn't be a problem. If anyone has any help hints that would be appreciated. Thanks.

If they are sized greater than 720x576, have QPEL or GMC, or high bitrates, are larger than 2GB, most standalone players will have problems. Sometimes if the extension is .divx, they won't play, then just rename to .avi

You can check with mediainfo (view=> text), and gspot to see characteristics of the working and non-working files.

If you come across these characteristics, the only way might be to re-encode them with the compatible settings

Any of the following may (or may not) be problems for Divx playback on standalone DVD players:

1) Resolutions greater than 720x576
2) Use of QPel (quarter pixel)
3) Use of GMC. Should be avoided although SOME players will play them if only 1 warp point is used. 3 warp points has never worked in any standalone player, despite claims to support it.
4) Packed bitstream.
5) File sizes greater than 2 GB.
6) High video bitrates. Anything above 2000 Kbps may not play. Use of any audio other than MP3 may require that the bit rate be even lower. DTS, for example, may require your video bitrate to be 1200 or less.
7) MP3 "weirdness" such as KHz other than 48 or 44.1, use of VBR, too low or high a bit rate, etc.

You can fix packed bitstream without re-encoding by using a program called MPEG4Modifier. Everything else will require a re-encode to fix. Gspot may be helpful in identifying if you have some of these problems.

Not all NTSC players will play PAL Divx files. Check the files with Gspot and see if the ones that don't play are 25FPS.
