The analog encoder is running with the tree form linuxtv.org. It has 
some cleanup video ioctl2 rework going on by another dev here, but it's 
functional as is. It's usable today.

Yes and yes.

Typically the analog video devices are exposed as /dev/video0 (analog 
preview) /dev/video1 (encoder output) and /dev/dvb/... for the digital side.

Trying to view analog preview and the encoder at the same time has some 
quirks, best to avoid that but other than that you should be good to go. 
I don't personally use Myth, so if anyone has any MyTh related tips then 
  they should chime in here.

Firmwares and stuff are generally available from
