How do I scan for QAM channels?

pcHDTV 3000 supports unencrypted QAM channels over cable. You must have the DVB module drivers (cx88_dvb) loaded to use QAM. [TODO add link to pcHDTV forums on DVB driver installation.] To scan for QAM channels:

1. Get the dvb-apps tools from cvs.

cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv login
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv co dvb-apps

2. Read the dvbs-apps/INSTALL to compile and install.

3. Save this channel.conf to ~/.azap/channels.conf.

You should be able to scan for QAM channels using azap (part of the dvb-apps tools). Run 'azap [channel]' to scan for a specific channel. For example:

$ /usr/local/bin/azap c88
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 609000000 Hz
video pid 0x0000, audio pid 0x0000
status 1f | signal f3f6 | snr fd27 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ef9c | snr fd2b | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal f3f6 | snr fd29 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

The FE_HAS_LOCK indicates a signal lock on channel c88. Cable channels typically begin at c80.

You can also use MythTV 0.17 to automagically scan for channels on your DVB card. Make sure you compile it with DVB support.

How do I know if a QAM channel is encrypted?

There does not seem to be a way to tell for certain. See this post and this reply (March, 2005).

How do I record a stream from DVB?

You can use dvbstream and dtvstream. See this post (March 19, 2005).
