Hi Further to my previous enquiries about the Avermedia A771-B DVB-T PCI (mt352 chipped) card under linux. I took advice from Brice and tried stealing the tuning info from the MS Windows Avermedia software and using that in the channels.conf file, and I also tried setting all the fields to AUTO for the scan program - with the exception of the transponder code which doesn't appear to want to go auto (guess you have to give the program a certain clue). Still no joy, nothing tunes and nothing locks on - although I'm a little suspicious about the tuning data from the Windows side - for instance it says BBC ONE is on *exactly* 610000 KHz (!) Anyway I appreciate there is obviously a huge hole in my understanding - I naively hoped I wouldn't need to understand much about the underlying broadcast technology of Digital Freeview, or any really nitty gritty stuff but obviously I do. However, I'm still a little suspicious of the setup - in that I don't really think the driver/linux is liking the card. Digital works differently from analogue (that I realise) - at least with an analogue card I could receive crap aka static so I would at least know that the drivers/applications were speaking to the card. I don't have that advantage with digital - OK perhaps if you're a DVB-guru you might know that: status 00 | signal a05f | snr 0000 | ber 00000000 | unc 00000000 | status 01 | signal e35f | snr 0000 | ber 00000000 | unc 00000000 |status 00 | signal a05f | snr 0000 | ber 00000000 | unc 00000000 | status 01 | signal e35f | snr 0000 | ber 00000000 | unc 00000000 | acually means something. My questions this time around are: 1) Does anyone have (a UK Centric) DVB-for-idiots type of guide, what transponder codes are, what multiplexed channels are. 2) Is there a basic simple program that will test a DVB Card. Nothing fancy, nothing that will try and tune or lock onto channels. Basically something nice and simple that will just go "Yup, I can see you card, I can see your tuner and I'm receiving rubbish and I can speak to stuff", basically so I know the card really is working. Thanks again for any help. Hugo
