Sorry, I can't help you with 51killer.
On the upgrade issue, you're wrong. The procedure I use:
Block software upgrades. When the new software version is available modify installSw.itcl to prevent the reboot, then run it to install the new software. Rehack the new software, then reboot. Watch your old recordings, new recordings, or live TV as desired.
There's a difference between needing help, and just being plain ole' lazy.
