I am having a very strange problem with the streaming of the CBS channels in Windows Media center 7. The issue is that when I go to channel 11.1 to view it live it will show that there isn't any signal but if I hit the record option then it wil start streaming and works fine. Basically I can only watch it if the recording is in progress. I had this problem intermittently (typically on Sunday afternoons) prior to them dropping the broadcast on 11.1 and switching to 19 at the end of November but now it happens all the time. I did a re-scan and it still shows that it picks up 11.1 at full signal strength. It also does the same thing with the other CBS affiliate on 27.1. All of the other channels stream perfectly. Any idea why this might be happening?
