Hi there,

My results with Nexus-S rev 2.3 and the the patch suggested in this thread:
- Loading module dvb_ttpci (and a couple of autoloaded depending modules) 
results in a silent "plop" (caused by activating audio out, I guess).
- Everything seems to work (no errors, VDR-OSD is shown) - except the tuner.

- Before loading dvb_ttpci there is no signal at all (0V).
- When I load the module, the card switches to 18,75V, but no 22kHz signal 
(due to my multimeter). By the way: Voltage isn't switched off on unloading 
dvb_ttpci and depending modules.
- There's no reaction when I try to tune with szap: lo-band, hi-band, 
horizontral, vertical polarisation. Nothing changes (voltage, frequency).
- I tried it with 0xD2 instead of 0x92 in alps_bsru6_inittab (posted in 
http://www.vdr-portal.de/board/thread.php?threadid=31057 - german language!)

- same result

Sorry, I don't know what you're talking about, I'm rather new in PC TV 
hardware concepts. Maybe someone could tell me what I have to look for.
Would 
it help to put the card on my scanner and mail a picture of it? But
http://www.ploeb.de/nexus.html should already do a good job.

Good idea. Below some output of szap. Probably not helpful - but who
knows...
