Hey, welcome to the forums.
Have you upgraded to the latest firmware? The most recent beta should show improvements in playback quality, get it
here.
There is a physical limitation of the OSD, it's unable to smoothly play files where the bitrate goes over 4000kbps. Videos are encoded with variable bitrates, so slow scenes are fine, but you'll see stuttering, during fast action scenes, camera pans and such. Depending on how you've encoded your avi files (what codec? avi is a container, it can hold divX, Xvid, and more), this might cause a problem.
You can make clips to send us (much appreciated by the way) using
VirtualDub (free), there's a nice guide here (pop-up alert):
http://www.divx-digest.com/articles/cutavi.htmlBest send us bits that you see playing poorly. Keep your clip under 10MB.
You can send Neuros this file by creating a bug in
Bugzilla (or if you find a bug with the same problem), and attaching the file to the bug.
Many thanks!!
