So I created a script to run rmmod tuner && modprobe tuner twice at the end of my init scripts. This sometimes works, and sometimes doesn't.

Yes, I've not spent much time looking into this to find out exactly when it happens. When I was messing around the other night I thought it was to do with switching from 'H' to 'V' polarisation (? is that the right term) but then it seemed to manage ok. >> Also, the picture quality on the HVR has a lot of artifacts in it >> (pretty >> much all of the time) whereas my STB displays the picture fine with no >> artifacts at all.

And yes, I agree about keeping discussion public. I've not seen either of your recent mails via the mailing list though (even though cc'd the address) ? > I tested the DVB-S stuff with an L-BAND modulator, meaning the 13/18v > output (or perhaps lack of in this case) was irrelevant.

I'm not overly familiar with all the technical details of how it works. (If anyone has any good "intro to dvb-s links" I'd be interested) I'm just trying to learn as I've only recently put up a dish and bought a box and amazingly it just worked :-) For what it's worth, I've got a "universal lnb" and I'm based in the UK. My dish is pointing at Astra 28.2E (I can also get Eurobird channels on my STB but I've not tried those via the PC yet) > Certainly, I have _not_ seen noise on the DVB-S transport unless it's > being introduced in the environment. I'll double check this also. I'll have to have another go with the card in Windows and see if I have the same problem with the signal - then at least I will know if it is something to do with wiring or whether it is linux-related. However I've managed to screw up WinTV2000 somehow and I don't think it will start up now :-@ So that might be a bit of a task as I will need to reinstall it. I'll also try connecting the lead from the dish directly to the HVR card rather than via the STB to see if that makes any difference, but I think I've tried this before and it didn't help. > It's been a while since I modified the 3000 patches (and they were a > little rough around the edges). Time for more fixes I think. Excellent :-) I'll look forward to them.
