I've been running a week now with flawless encoding, channel changing, 
livetv, etc.

Just to summarize my TBS2603 install:


- MythTV 29 works WAY better than 28. If you use this device, I'd say 
your minimum install 29

- the Wiki page is overly complicated because the scripts power up and 
down the STB. If you don't do that, you only need a recording started 
script.

- My recording started script is this:
