My two euro cents follows.


My channels.conf says:

My syslog says about my dvb cards:

I am running VDR 1.3.23 with some plugins.

My kernel is "2.6.11.6-kraxel1", with DVB driver patches from bytesex.org.
I had to install this bleeding edge driver stuff in order to get the
new Hauppauge DVB-T cards with conexant chipset to work.

I tune to a dvb-t channel to avoid _viewing_ of the HDTV channel
and create a timer to record a sample of the HDTV transmission.

The result: I get lotsa data on my hard disk. :)

Watching TV from dvb-t during the HDTV recording
becomes a mess, though. The picture and sound will stutter
VERY badly during HDTV recording. After deleting the timer,
vdr will behave normally again.

Linux mplayer seems to playback the HDTV reconrding (almost) properly,
so the stream seems to be ok. Sound is working too.

Switching "livetv" to the HDTV channel will mess up the screen completely,
which was what I supposed. VDR or the firmware does not seem to crash.
I can get VDR to change to another channel after quite a long
delay after pressing a remote control button.

P.S. what is this?

I don't have the Canal+ movie channels enabled on my smartcard right now,
so I could not test this myself.
