Advertisements I am guessing this is a computer issue, not a Tivo issue. I installed Tivo Desktop on my Windows XP system. I transferred shows to my computer. I hit PLAY and Windows Media Player 11 opens and I see it says something about the codec being acquired. Then nothing happens. In WMP, if I look at the file properties, it says Length: 00:00 and Media Type: Audio. Downloaded video from the internet works fine. Any ideas? Thanks, in advance.
