Is there a non-flaky AVI player for iPad?

I have tried the VLC player, CineXplYer, yuvplayer and all are flaky as hell playing AVI files.

VLC crashes at all odd times or the images are jerky and sound not synchronized.

CineXplayer is no better. It suddenly shows corruption onscreen and then the movie continues with no sound. I have to restart to get sound till it happens again and again. Some 1/2 hour TV series I downloaded stop numerous times.

Why are such flaky apps allowed on the app store?

The movies play with no problem on my PC with windows, yet so much hassle with the iPad. Even converting them is flaky with other odd problems that show up and besides I don't have the time to spend hours converting to mp4 only to find other problems.

Any suggestions are welcome.
