When I go to watch TV through the placeshifter client on my local network I can tune in to a channel without any problems but when I try changing channels I get timeout and read exceptions. In order to change a channel I have to stop playback and select the new channel from the guide. Does anyone have any idea why this might be happening or how to fix it? I'm running the latest version of sagetv and placeshifter. I also have Ubuntu 6.06 with kernel 2.6.15 running IVTV firmware version 0.4.6 for a PVR500 card. Thank you.
