Done. You can find 'messages' here: http://www.rockhopper.org/messages.txt Unfortunately not really explicit for a newbie like me, maybe a specialist on this mailing list can have a look.

No programs seems to work (unless szap that is reported to be OK if FE_HAS_LOCK). By the way, I've removed for tests the CAM module and TPS smartcard. Any hints? Thanks again.

Hi i can only speak of the dec2000t but as they use the same driver and about 90% the same code they should share most of the problems :/ There are some problems with section filters which dont work properly in some cases that might explain why the scan fails. (Although iirc scanning worked with dec2000t last time I tried.) But you might try to look for a channels.conf for your area in the internet instead. About missing features: - you wont get any status information(signal quality, signal lock etc.) - no teletext - pid filtering is somehow limited, as you cannot set the filter to any arbitrary pid, but you are limited to setting the video/audio/pcr pid filter. which might be a problem with some applications. - no support for the CI of the dec2450t and the dec3000s, so no support for any encrypted channels. about stability: it works quite well if you just watch, but the box very much likes to hang if you are zapping around. This also happens under windows but not that often and reproducible as with the linux driver. According to the linuxtv wiki it is at least partly a hardwary problem as the AV711x chip is a "quite sensitive beast and hangs often". Although atleast with the dec2000t these hangups mostly vanished with newer firmware & software versions under windows. So there are certainly some parts in the linux driver which are "wrong". Some things you could try: - if the box shares the usb bus with other devices try to remove them, so that the box is the only connected usb device. - as said above try to get a pre-made channels.conf for your area and try if simply locking into a channel with szap and the viewing with mplayer works - load the ttusb_dec module with debug=1 and then send the relevant dmesg output after you ran the szap/scan command which might give a clue what excactly doesnt work.
