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
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
