AVI file gets really choppy / other problems with random avi files

i did a quick look around and didnt see anyone bringing up the same problem im having, i know that avi files are just a container file and thats why some are fine and others arnt. 

The biggest problem is with some of the AVIs i have right from the start they are either super choppy (aka barely doing anything video wise maybe 1 -2 frames per 5 sec)  or they play a few frames then stop playing video and just show whatever frame they are on, either way the audio plays fine. 

below is the info for one of the files i know for sure has the problem

i dont know the exact firmware version, i bought it for my parents and so its at their house, i did update to the latest firmware the day i got it which was  5/13/2010

it also had problems playing an mkv file, but i read on another thread that anything muxed with mkvmerge had some issues so it may just be that (said file was muxed with mkvmerge)

in another threat i also saw someone say that the wd tv live doesnt really care for mpeg-4 files, but they didnt really describe what the problem with them was… if thats all this is, would a simple re-encode to something more suitable fix the problem?

Welcome to the forums.

Files produced with mkvmerge are not an issue – I use it all the time (with every file, in fact).

I assume these are files played off a local drive, correct?  If so, you can try this test: encode using Handbrake using the High Profile (only change output type to MKV).  If the subsequent file plays find then at least you know it’s not the Live unit at fault (that’s the gold standard of compatibility).

sorry about not replying faster, been kinda busy last few days. yes its a locally attached usb drive. ill work on getting some of the ones i know are problematic reencoded and ill probly stop by my parents house this weekend to test it and reply with the results.

Ah, since you last posted we did find an issue with the latest version of mkvmerge – with the default settings of compressed audio track headers there are issues (so turn this off or use an older version).

That may be the problem, or it may be something else.
