Ok, I recently upgraded to Tivo Desktop 2.5 on my Vista laptop. Everything is working great (music, pictures, even ToGo transfers from TiVo to my PC) except the new divx playback features. I remember in the past, using 2.4, seeing my computer listed in the Now Playing list. Although now it doesn't show up at all. I can see my 2 TiVo's from the TiVo desktop software and even transfer programs. I have disabled anything firewall related (I was only using the included Vista firewall anyway) and I'm not running any other security software. Any ideas?
