I considered an external channel changer, but couldn't find one that
worked perfectly. I did find one that worked after updating the source for
my specific model but it dropped the 5 in any channel >499. I've had good
luck with the internal SA4250 channel changer so far. I just wish I didn't
have to watch this thing constantly as the only warning about failure I
get is a recording with size 0bytes in mythweb.
