[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 
and timeshift).

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.
