I haven't been using Tivo Desktop for some time and I just went back to check it out. I tried to play some old files I transferred at the beginning of the year with Windows Media Player and all I get is audio, no video. I transferred a current show from the Tivo, tried to play it and the same results. I did find one posting that suggested installing mpeg-2 codec, but they wereinstalled already. Do I have to check some settings? Download additional files? What gives?
