I upgraded to Desktop Plus today and was happy to see that all of my home videos recorded in .wmv and .avi now appear in the Now Playing list on my PC. All of the files are playable on TiVo Desktop Plus no problem. I click them and they play. However, when I bring up my Desktop Plus selections on the TiVo, the .avi files have the old ghostbuster sign next to them (not the .wmv files, they're fine). When the .avi's are selected for transfer on the TiVo I get the message: "Transfering prohibited by the copyright holder".
Since these are recordings made by me, and I'm the copyright holder I don't know what's going on.
Here's my setup:
TiVo HD
Desktop Plus on a Windows XP
All other files transfer with no problem, including WMV files.
Oh yeah, and when I convert the .avi's to .wmv's they play fine too!
