I found a work around that avoids the error message entirely:
When I start "Watch TV" I am on my first cable tuner. If I type in the channel number of a channel that is only available on the
south antenna tuner, it will automatically switch tuners and then tune the channel properly, even if it is HD and the previous
channel is SD. I can then type in an HD cable channel, and myth will automatically switch back to the first cable tuner, and
tune in the HD channel properly. After that I can change channels without fear of running into the dreaded "Error opening jump
program file buffer".
I hope these work arounds give clues to the actual problem so it can be fixed.
