Hi everybody,

I first posted this message in german. Sorry for that. Was a mistake.

I have a discussion of the problems explained below since some weeks inside 
vdr-portal. There also a lot other people with the same problems and nobody 
could give us hints so far. So I decided to try to contact the doers of dvb 
modules and firmware. If you are interested you may find the discussion at 

http://www.vdrportal.de/board/thread.php?threadid=35877&sid=&threadview=0&hilight=&hilightuser=0&page=1

I am using kernel 2.6.11 and firmware revision f. The drivers are those 
shipped with kernel. I am using a Technotrend DVB-S 
premium card, revision 1.5 with mit VGA-output (christmas offer from 2004 at 
dvbshop.net). The mainboard is an Elitegroup KT-600A. The software I am using 
- as most others - is vdr. The version of vdr I am using is 1.3.24. I also 
tried 1.2.6 and 1.3.17.

Here are my problems:

1. Sometimes there is only a black screen delivered from vdr. Often I am able 
to use vdr as usual (start recording, start playback, OSD etc.) but there is 
no picture of current TV program at all. Sometimes vdr even doesn't react to 
anything.

2. The are some situations where a still picture is shown with a small bar on 
upper border that changes.
 
Sometimes I could get rid of the problems by restarting vdr. Somtimes I have 
to reload the module dvb-ttpci. Sometimes the still picture effect solves 
itself. In neither case the vdr watchdog is released.
 
When I run the femon plugin in such a situation I see that S/N and SNR are 
well and the status signals (Lock etc.) too. When unmounting the satellite 
cable all signals go down to 0 and the status displays become red. After 
reconnecting everything is ok again and I get immediatly a picture.
 
So I think it is no issue of satellite system itself.

The CPU temperatue in my system is around 45°C. So the air inside case should 
be around 30°C which is acceptable.

When having a look inside my syslog I find the following entries from 
dvb-ttpci :

I would like to find out whether these problems are known or if I have a bad 
piece of hardware. I also would be willing to offer my hardware for a certain 
time when it would help t osolve the problems. Perhaps all developers have 
different cards.

Thanks

Ralph
