What type of setup do you use to pass the data to the TV if you're not 
using the PVR-350s MPEG decoder? What would prevent you from having both 
decoders active at the same time?

In my experience, the caption data is not present in the video signal 
unless you are using the built-in MPEG decoder; with that option off 
it's not passed on to the TV for decoding so you're forced to use Myth's 
built-in decoder.
