How much of this are you doing with myth?

I'm doing the same thing and the results of either FW or SV are great but 
I haven't ( yet ) been able to come up with a nice way to switch between the two.
In other words, I can do a for FireWire setup or one for S-video ( changing channels 
with the STB remote and manual start/stop ) but the S-Video method is very much a 
work in progress.
I have a DCH3200 and a DCH3416 both set  up as OK with my cable company.
