Last night I took another hack at getting MythTV working with my DVB card. This time I was much more successful! The key was configuring Myth to use the LNB, which was hidden in the mythtv-setup under “capture cards-DiSEqC options. An LNB is not a DiSEqC, so I would’ve never thought to look there, but there it was.
MythTV was really built for DVB reception, both DVB-T and DVB-S, so it’s really in its element here. I fed it a custom channels.conf (generated by the dvb-utils’s scan app, which used a hand-made list of satellite transponders for input), and Myth not only scanned the channels I provided it but proceeded to tune all available channels from the satellite. I was pleasantly surprised when this process took less time than I expected. It even picked out the modulation and error-correcting modes of each signal automagically.
Myth’s impressive satellite scanning ability gives me confidence to install another dish and attempt to pull down some Ku-band wildfeeds. Anything that’s broadcast for a couple of minutes should be easily discovered by Myth, especially if there’s a known number of transponders to scan.
Geeky good times, this stuff.
