jerky AVI, smooth VOB (DVD)

[Tau]

Hi and thanks for reading my post!

I have this weird issue: when I play a DVD in my PCs DVD-drive, the video moves smoothly. But when I try to play an .avi movie from a DVD disk, the video and audio gest "jerky". When I copy the AVI to HD, the problem is gone. I'd been thinking it may be because of the file size (VOBs don't go over 1GB while my .AVIs may go up to 2.5 GB), but this problem occurs even with small .AVIs (e.g. 700MB) Maybe the AVI bitrate is too high and the drive cannot keep the stream of data going? Or maybe the data on professional DVDsare better layed out for reading than my personal Nero-burned data DVDs? I'm in the woods.

Could somebody kindly help me with this please?

Many thanks in advance!

My specs: WinXP, P4 1.6GHz, 512MB RAM, Toshiba DVD-ROM SD-M1612 (48xCD, 16xDVD).

I had the same problem, I have a P3 1.4 machine and just assumed it didnt have enough grunt to play avi's. But infact it does, it was to do with my video card (old nvidia TNT), it didnt like directX 9.0b, played DVD movies nicely, but couldnt play AVI's (too jerky) - switched back to directX 8.x works!

Anyway may not help, just passing on my experience...

Switch off postprocessing.

"Switch off postprocessing."

Where would you find this?

known_03,
What player program are you using to play back .avi's?
Look for configuration of your player.

I use PowerDVD and classic media player (latest version), both didnt work correctly with AVI's

in classic media player try setting in OPTIONS and FILTERS

edited: and upgrading to Direct9 and to use DirectShow filters efficiently you must go to Windows Media Player 9 also, or you can try beta WMP10.

Hi!

Thanks for the replies!

I did several more tests and it appears my system can play smoothly .avi files with lower bitrate - that means less data going thru the pipeline.
