Take a look at the transponder file for your local transmitter.

I personally do not like the Hauppauge Nova-T and all others using the same design, they need a very strong signal before they'll tune. Anything using an mt352 frontend will tune well, and the other card I have, a KWorld V-Stream is one of them (be warned, there are two designs for this card, the one I have, and one similar to the Nova-T). > 2) Is surround sound available for DVB-T and are there cards and Linux > drivers that support this (what about that nice Terratec dual card)? That's all dependent on the broadcaster. All modern DVB cards do is take the mpeg stream from the airwaves and present it to the application. If the mpeg was broadcast with say a Dolby Digital 5.1 sound signal and your software knew what to do with it (mplayer certainly would), then yeah, you can get surround sound. So it's a combination of what is being broadcast and what software you're using. > 3) Same questions with the features "VideoText" and "multilingual > audio) (e.g. theres arte in Germany and France which broadcast nearly > everything in German and French, in both countries) Same thing as no.2. If this information/audio is broadcast as part of the DVB signal, and the application knew what to do with it then yeah, it'll be able to use it. I don't believe there is currently an application on Linux that can view videotext/teletext that is broadcast on dvb, but certainly mplayer and perhaps others can handle multiple sound streams. > btw: Any information if Linux drivers will support that dual DVB-T? That's largely dependent on what information we can get about the card, who's got one, and who's got the time and skills to put into development. That said the picture shows Thompson tuner modules, and we already support at least one Thompson tuner (the one on the Nova-T), so it may not take too long to create a driver :) And finally, I was wrong about the PCI DAB cards... At least two PCI DAB cards have been released but neither seem available at this time. There have been at least two USB DAB receivers released, and again neither seem currently available, though it was suggested that they may be available on eBay. I'm going to try and get hold of a USB DAB adaptor and write a driver for it. If someone can get me a PCI version for very little money, and be able to get an agreement to get programmer info out of the manufacturer then I'd be happy to give the PCI card a go too.
