First you need to know the freq for QAM  best way to find these is wth
the channels.conf for qam floating around, I guess I'll try and attach
it here.

In there you will see the freqs.

to record a stream I use the following command which  found over at
the pchdtv forums I believe:

$ dvbstream -v -qam 256 -f 759000000 -c 0 -o -n 15 8192 > 118.ts

the -f 759000000 is the freq, so change this to correspond to the next
channel.  (I think they are 6000000 apart, so just add or subtract 6
from the 759 to get the next channel)


$ dtvstream -i 118.ts -o 118-1.ts -R

dtvstream will list the sub streams and prompt you for a stream ID.

also you can use mplayer to view:  $ mplayer -tsprog  # 118.ts  where
# is the stream number.  to see the available streams, just do this:

$ dtvstream -i 118.ts -q

hope that helps.

getting them into mythtv is another issue, as channel scanning didn't
work for me.  there is a tread about tuning QAM subchannels in the
archive that has some insight into that.  Also check out the pchdtv

Good luck.
