Grainy Video Playback! AHHhh

[sony2k3]

hey guys..i have a serious problem here. I've tried several codec packs and i have tried just installing individual xvid, divx, etc codecs but my video playback for all videos (xvid, dvix, mpeg...) all turn out to be this quality. what is going on?? i tried gspot..but everything is fine and ive also updated my video driver. i have NVIDIA GEFORCE4 MX420. please help! thanks a bunch

that looks to me like its just a bad avi copy of that film in particular
have you tried other one's you know that are definently excellent quality???????/

looks like the bitrate was to low when encoded. lot of macroblocks in the waves (action scene). IMO I think some ppl use to low of a bitrate, to encode to mpeg4, to get a small enough file to fit on one cd-r

nonono..ALL My movies are like this!! regardless of codec. ive tried them on my laptop..everythings FINE!! argh..please help

have you tried looking at the post-processing options in the divx's config.exe?although that wouldn't explain why xvid's are like it too, and even with post-processing at minimum it shouldn't look that bad

If everything plays fine on your laptop then I'd assume it's a problem with your other computer. But what ? what resolution is your system set at. is it a faulty video card. what version of direct x. how fast is your cpu. could you post specs on your computer so we could look at it.

My Specs

hey..my specs are:

2.53 Pentium 4
directx 9.0b
nvidia geforce4 mx420
resolution 1280X1024 on 32 bit color
updated nvidia drivers
512 ram

surely enough computer. everything looks good. as an experiment try lowering your resolution to 1024x768 and 800x600. this only happens when playing a video ? I'm just taking a guess but if this only happens playing video files then it has to be the way you're system's processing them. Do you have another video card you can try ? Never happened with geforce card but my ATI drivers I had to uninstall and reinstall a couple of times.
continue to keep us informed of your success.

hey thanks alot for taking time to look at my problems. unfortunately, the problem hasn't been solved. i tried lowering resolution but i have a feeling that it has something to do with the updated nvidia driver. i've uninstalled/installed the video drivers several times. but i think this problem arose only after i updated the drivers. if anyone has access to old drivers please let me know. once again thanks a lot.
