Cannot check that precisely. If you have a look at http://home.vrweb.de/~rnissl/images/pa150070.jpg you can see part of my development system. It's a micro ATX board in a desktop case with cover removed for several years already. The cards from right to left are, GF6600, SkyStar HD, NOVA-S CI, Netgear WLAN. I've put the AUX temperature sensor of my board between the two DVB cards. The sensor reports ~ 50 °C. > I guess the the back paddle (the STB0899 sinks the heat on to the PCB, > there is a metal flange at the backside of the STB0899, which is soldered > on to the PCB, through the thermal via's.

A reboot or a power cycle solved this issue most of the time. There was just a single case when I had to power off the system several times. > Read on, there is a comment from STM on this, check this as well. > >> stb0899_get_dev_id: ID reg=[0x82] >> stb0899_get_dev_id: Device ID=[8], Release=[2] >> >> It may take several weeks of normal use before I can report success or >> failure.

This is how I load the drivers in VDR's runvdr script: # Load all DVB driver modules needed for your hardware: function LoadDriver() { make -C /soft/src/v4l-dvb load # make -C /soft/src/v4l-dvb debug } > Some demods are very sensitive to such things. if so try removing > all such cards.

Well, I don't boot into windows that often. The installation is basically meant to install the accompanying drivers to have a check whether the hardware is working. So far, it was always working with windows. But I think, since March 07, I've only booted about 7 times into windows to "watch TV". And I think, that I've rebooted Linux about 7 times over that period when the card was not working properly. Since July 07 I was using this card with VDR and powered off the system on a daily basis. Regarding tuning to RTL transponder: it works in windows like the tuning to all the other DVB-S and -S2 transponder. > This was another suggestion by Peter (STM): > > "Check the back paddle is properly soldered.

If I get you right, then I should not push the IC just for fun as it or the card could get damaged. > (Head is spinning now, strange indeed what you see) Thanks for your support.
