choppy playback

[eon]

I recently bought a new computer and started to play divx/xvid/mpeg files and they were choppy and distorted. I tried a bunch of things and thought it may be the codecs but the codecs are fine. After trying a million things and losing it, I decided to turn down the hardware acceleration in the display settings. That worked and I can see the videos without distortion, but they look like crap without the hardware acceleration (So Bad that I'd rather not watch the movies that way). So I had to put the hardware acceleration back up. I downloaded Virtual Dub and loaded the videos in (with hardware acceleration FULL) and the videos looked fine within Virtual Dub, however, when I try to play them on Windows Media Player or the DIVX 5.02 Player or BSPlayer they have this distortion to them. Has anyone had this problem, does anyone know how to fix it? Note: I have a Pentium 2.8GHz, Raedon 9500 PRO, Sound Blaster Audigy 2, and a Planar Monitor. I'm sure all the drivers are in correctly because I did the Microsoft DX diagnostics test and every test passed (Direct Draw, Direct X, and Direct Sound). Any help is appreciated.

Might have a solution for you!

Hello EON!
I have some questions for you.
Does this choppy playback apear on both DivX, XviD & OGG?
Or is it only on XviD?
What OS are you using? Win2K, WinXP?

Welcome to forum Eon.
Sounds like video overlay issue. (drivers)
Get a good set of drivers for radeon here.

To confirm its overlay issue, play movie in media player and press "Print Screen"
load into mspaint or similar and goto 'edit/paste'
If the screen is black, overlay is ok.
If it's not, then its a video driver issue.

Also, download the ATI Catalyst drivers from the ATI site too.....version 3.5

Good luck

try ffdshow.

download and install it, then go to the ffdshow config. under codecs, select all that you need (Divx, Xvid, .....)

play your file see if it will work.

Overlay

I did the print screen thing and it is choppy in MS Paint. I'm not sure what that means. I guess it's an overlay issue, but how do I fix that? In response to the other questions. I am running Windows XP Pro, and all files not just XVID play back choppy.

I must agree that it is a video driver problem. Don't trust the simple DXDIAG if it says everything is OK, Only trust it if it says they are not.
If everything is working correctly, print screen should NOT capture the movie data ! If you use MS paint and paste the image, it should be completely blank (make sure you closed the player that you used to capture the image or it will show through because of the overlay).
Corrupt video driver installation usually occurs due to an initial bad install, or conflicting files from a previous installation of an earlier version of drivers.
To make sure you get rid of any files from a previoius version, first make sure you uninstall your previous video drivers before installing your new drivers.
If that fails, I have heard that if you set your video drivers to the Standard VGA drivers that come with Windows, then reboot, and install your new drivers it will fix some problems.

ATI tech support would be the best people to confirm this.

P.S. If you turn down Hardware Acceleration for video, then the movie data will be in the Windows video buffer instead of the video card memory and can be captured from print-screen, but frame rates are usually terrible. (only recommended for when you want a screen capture of something cool looking)
