Basically it came down to a shortage of cabling. S-Video don't carry 
audio along so it required yet another cable to go from the RCA->DIN 
plug. I switched to it after purchasing a cable and that appears to 
work. After digging through the setup once again it _looks_ like I just 
had it misconfigured to not tune to the correct channel. I dug in the 
source a bit and all the calls V4L calls look right to do the tuning. 
(Just a quick glance). *shrug*

>I'm just starting to play with myth, just got it all installed last night but haven't spent any time with it yet.  But up until now I've been watching DirecTV using xawtv from the svideo input and the picture quality is FAR better than the modulated coax output.  I'm hoping (surely?) that myth can select the svideo or composite inputs as its capture source, since v4l supports it.  Then I plan to build a cable and write a plugin/script/whatever to change channels on my Sony DTV receiver via the data (serial) port.  I've already found the documentation on the web of most of Sony's serial commands to control the receiver.  The ever popular RCA DirecTV receivers can be controlled in the same fashion, although the protocol is different.  SnapStream even sells cables for many of these receivers, but I don't recall if Dish receivers are supported or not.  I like the hard-wired cable solution better than an IR Blaster solution.

Not an option with the Dish recievers that I can tell. No ports on the 
back for said solution, I got an Tira-1 on the way and we'll see what 
sort of battles that will be to get to work.
