client live tv crashes on channel change

[Etacovda]

goes to change channel, on stb by using up or down arrow, changes channel, number appears on the screen indicating channel change from stb, video freezes and crashes. Fine if i go out of live tv and enter it through the guide or what have you... attached logs from both pcs.

also noted that if i try to watch something from the tuner on the server (htpc in lounge) after its crashed on the client, it just brings up a blank screen (but allows you to watch)
