Thanks Jack, at least hearing that someone else is seeing similar issues gives me a bit more confidence that my system is not just totally screwed up.
For what it's worth, I sometimes see symptoms similar to what you are describing, in tuning or changing channels. But, I frequently upgrade to the latest svn release, so the behavior I see changes frequently. Last night I could not get MythTV to change channels. When I went to live TV, it would show the initial channel it tuned, but if I tried to change to another channel, the backend would generate a ton of error messages about not getting data from the dvb device. So, with mythweb, I selected two seperate HD channels to record simultaneously (I have an HD3000 and a FusionHDTV3 tuner cards) and that worked great. I could go in and view recorded programs, but just not live. On 9/6/05, Jack Perveiler <[EMAIL PROTECTED]> wrote: > I see something similar to this problem.
