1) I would *love* to get a copy of your settings.txt.. I have been looking
at the us-cable and such, but haven't figured it out.. If what you are
saying is true, then the composite1:xxx functionality is pretty much done!!
2) I've seen this really cool functionality that i think means that mythtv
*does* change the channel. check this out:
Insert the following line into "settings.txt"
What is cool about this? Every time you change the channel, the channel
number "echos" where it didn't before!! So, let's say you want to transmit
a "change the channel, dummy!" to your receiver, this command seems to be
I'll keep you guys posted on my trials and tribulations out here! ; )
