Doing a search in this forum for "Quicktime" resulted with this:
PQV

Note: it says "Ability to view
certain AVI and MOV (QuickTime) video files. I wouldn't count on being able to play anything recent. Also the couple users who tried it said it either locked up or gave a memory error.
As with all other video formats - you're best off having something specifically designed to be played on your Pocket PC instead of relying on your Pocket PC to resize/resample a video that was intended for viewing on a desktop system.
Also, PocketTV is strictly for MPEG-1 videos, nothing else.
