Thanks so much for adding Media Player and I am very excited about this addition to ATVflash!
Plyback goes out of sync if I pause and then restart a file. The sync slowly comes back together over the course of about ten minutes. This has happened to two .avi's I have watched. Also, one of the avi's was getting terrible artifacts and ghosting, something that would often happen to my ATV1 if the MP4 playthrough was on in the settings.
Keep up the great work, I look forward to the updates.
