Good point. I had been assuming that if I subscribed then it would be
available for recording. I suppose that's not necessarily true.

There are no posts on the link you gave for the Bay Area since April,
2008 so that's probably all changed.

Once possibility might be to tune the STB using either 1394 or the IR
Link and then record in analog using my old PVR-150's? Same quality
we'd get from the free tuners but access to all the subscribed
channels I think...

Thanks,
Mark
