ohh i don't know about that, i don't use the live TV part, just the sports part.
EDIT: it appears that when you click on links on the live TV part, it opens up a new window and you have to have the TVU player extension installed. unfortunately skyfire doesn't handle that.
TVU does have a windows mobile app, but i could never get it to work. your welcome to try though

EDIT 2: It actually does work, the video just skips alot lol, if you let it play for a few minutes though, it starts to play just fine. fun to play around with at least lol.
