Somehow the incorrect CBS station was in my lineup so I decided to rescan. BIG mistake. I lost most of the mainstream channels. I went from a little over 100 to 63 channels, most of which I would never watch.
Multiple rescans yielded confusing results - each time the result was a different number of channels, from 61 to 73. The 73 result was after I deleted and readded the source.
I then went into the list of TVE stations and tried to rescan them individually and 20 were successful, which were most of the channels I needed.
I even updated to the latest prerelease software.
Any thoughts?
