After many hours wasted trying to get MyDvd to work with Tivo Desktop 2.1, I read here that I needed to roll back to TD 2.0. I went into regedit and removed all traces of both Sonic and Tivo and reinstalled MyDvd 6.1 and TD 2.0, and re-transfered my tivo shows from the set-top box to the PC. Now the problem's even worse. Before I could make it to transcoding the video and audio before the program mysteriously crashed; now MyDvd hangs at the "Creating Movie" stage - well before I've even started the burning and transcoding process. Seems the problem is isolated with Tivo - myDvd will burn data discs and make DVDs just fine from some other (non Tivo) Media Center downloads I've got on the PC. Any thoughts, ideas or suggestions would be appreciated. I've tried Sonic support , but the online ticket I created is sitting there gathering dust, with no one assigned to it. (Appalling. ) I have to accept that Sonic myDVD is glacially slow and the push of any button appears to result in a full disk defrag, but not to work at all is a bitter pill to swallow after paying full price.
