What do you need to play *.avi files? I tried Windows Media Player, but it said it was "Unable to download an appropriate decompressor." and only played sound. Please help!

Always check source

by Sai P.S. In reply to AVI

Whenever you acquire a movie file, always check at the source in case any special codec requirements are mentioned. That way you wont end up with the frustrating routine of watching Windows Media attempt to download a codec.

Check Download the DivX driver and player (Standard option is more than enough). I am guessing this is the format of your AVI for two reasons:
- It's a format for which the MS Media site does NOT have a codec.
- It's a highly popular format since it offers quite amazing compression/quality.

Good luck.

I downloaded the divx player and tried running it and it gave me an error message that said:
"This program has performed an illegal operation and will be shut down"
"DIVX PLAYER 2 caused an invalid page fault in

Run Win Media on the file

by Sai P.S. In reply to Divx

Even if the DivX player does not run (for some unknown reason - what O/S are you using?), you can still try opening the file with Windows Media Player and if the format is DivX, it will use the new divx codec that you installed on the machine.

Definitive Answer

by GuruOfDos In reply to AVI

AVI stands for Audio Video Interleave and is a 'method' NOT a 'standard'. I could list 39 different known AVI formats, and Win Media Player can handle 7 of them!

You need to know what format the AVI file was encoded in, whether it was a hardware or software compressor that was used and do you need a hardware decoder to decode it in Media player (FAST AV2000 format AVI's MUST have the hardware card present to replay files, for example!).

Additional codecs are available for some formats, but if it was a hardware encoded format, you may need the hardware card to replay the file. Most AVI formats interleave the audio in standard PCM format which is why you can play the sound part of the file, even if you don't have a codec or the hardware to replay the video stream.
