I have something similar. When scanning for channels I show a sub channel of 26.4, (virtual 26), for PBS out of Winston Salem.
It shows up on scans with all 3 tuners I've used and the signal meter software for my Hauppauge PCI tuner card shows 100% strength and a SNR of 33+. I get programming on the main channel 26.1 and subs 26.2 and 26.3 just fine.
All the channel guides I've checked, TV Guide, the one that comes with both Windows Media Center and the Hauppauge software all list that sub channel with content that is programmed and broadcasting.
But when tuning in to that sub channel all tuners say "no signal detected". I've just thought that it was an error of some sort. But if others have similar issues, could there be something else?
The PBS main source is in Chapel Hill on virtual channel 4.1, with subs 4.2 and 4.3, no 4.4. Which is why I had thought some error with it being listed in guides but no programming being broadcast.
It was my understanding that channel 26 was just a translator/repeater, the PBS network here in NC has dozens all over the state so everyone can get the UNC-TV network feed.
