[mythtv-users] Problems with Tuning my DVB card for MythTV

Thanks for the info. I've got it working now. Works really well in Xine
and only drops frames occasionly. When I watch LiveTV or recorded shows in
Myth they stutter a lot as the CPU maxs out even though it only uses 6->12%
of CPU when recording a scheduled program.
Any tips on getting a smoother picture or am I doomed seeing that it's
running on a P3 1Ghz with 392MB RAM?

I have one of these cards. Here's a cut&paste from a previous message of
mine, maybe it will help.....
http://www.users.on.net/~jani/dvico-mythtv-11.html is a good resource,
and it got me working.
I just got a Twinhan DVB-T card working (in Australia). What I did first
was get it working outside of myth. If you have had success with tzap,
now use scan to generate a channels.conf file, example...
./scan dvb-t/canberra-au | tee mychannels.conf
Scan is one of the standard DVB utilities (see http://www.linuxtv.org/ -
maybe download the linuxtv-dvb-apps just to get the readme on scan) The
canberra-au example frequency list should be close (for me - just the
SBS freq was wrong, but once I corrected that, all went well)
The channels.conf file goes in various directories, depending on what
app you are using, for example, put a copy in ~/.mplayer and also one in
Another good test for the basic DVB functionality is to fire up
kaffeine. If DVB is awake and available, there will be a DVB tab in
kaffeine, and it can scan for, and play TV for you (as well as record
If it is all working, then when you run mythtv-setup, you can import the
channels.conf into the channel setup section. This is where
http://www.users.on.net/~jani/dvico-mythtv-11.html#ss11.5 didn't work
for me. In the channel setup section where he manually configures the
channels, I imported the channels.conf (I think the option to do that
was under an advanced button) Must be a feature in later versions of
myth - mine is .18.1
The only left to do then is get the tv grabber working. When you have it
working and retrieving XML, go into mythtv-setup, set it up as a source,
then go back to channel setup, and enter the XML ID for the channels
with guide data. I grab data from d1.com.au, and I get program info for
all the basic channels.
