I was trying to convert a GIF image (Ajax waiting like) to AVI that will be used with TAnimate control (I noticed your program is in Delphi )
The AVI looks fine, but it is not transparent when I don't use windows XP Themes manifest (I use D5).
the Common Avi's are transparent even if my program is not themed. I also have a few custom AVI files that looks transparent.
on MSDN it's stated that: "AVI file that was compressed using run-length (BI_RLE8) encoding." (RLE 8bpp RGB)
Is there something I can do to resolve this issue?

When you don't use XP themes, an older version of COMCTRL32.DLL is used, and it probably doesn't support recent AVI formats.
You can try to change the format of the AVI made with AniTuner, thanks to an AVI editor like VirtualDub for instance.
