Today I added AVPlayerHD to my iPad1 (OS 5.01). Install and first wireless file transfer went smoothly. However, the 80 MB file (.wmv format ) which plays well on Windows Media will not play in AVPHD. Clicking on the file brings up the player screen for just a second or so, and then the app closes. I deleted and then re-transferred the file, but same result. The file is not HD - it shows up in AVP as 704 x 396. Could this be the problem, or is there something obvious that I am missing?
