I'm pretty sure the new nova-t works well now. In terms of the TV they both seem to work equally well. I can't do a signal strength comparison because for some reason the statistics tzap reports are rubbish on the Vision+, which is a shame. Doesn't stop any of myth from working though. The main difference between these two comes down to the remote. The nova-t has a very nice small remote which is almost perfect for mythtv (short of volume buttons unfortunately, though you can remap 2 other unused buttons). The receiver for the remote plugs straight into the tv card, so this remote will only work if the frontend has the nova-t card in it. The Vision+ comes with a remote that's certainly not as nice, and unfortunately is almost entirely useless with mythtv. The receiver is completely separate from the tv card and plugs into the usb bus, which is a great start. Unfortunately it behaves as a usb keyboard with fixed and somewhat useless key mappings. Maybe you could remap all the keys in myth to suit it, but I gave up with it since it didn't work with any other remotes anyway (eg. the nova-t one). > Or should I just go for the cheapest? Shouldn't the outputted MPEG2 stream > be identical for each card? Yes, it is. It comes down to three things: i) driver support/quality ii) reception iii) remote I'd say nova-t & vision+ are pretty close on the first two, large gap on the third. If you're using a separate remote receiver anyway (or have your tv cards in a separate backend) then get the cheap ones for sure. > The option to receive some of the top-up-tv > channels might be good too. Has anybody got this working yet? Not as far as I know. But then it seems an awfully large amount of money for virtually nothing in terms of decent programming.

You don't need as much disk transfer speed as maybe you thought. Even laptop 4200 drives would work. The MPEG stream comes out as about 500k-1MByte/second, which is massively under the 25MB/s you could expect even from a slow disk. Recording from a DVB card to disk takes almost no processor (it's not all that far from doing 'cat < /dev/dvb/adaptor0/video0' > /video/file.mpg'), so watching while recording is usually a non-issue. > I'm guessing I won't need any soundcards in a DVB only system? Well you need to get sound out somehow - maybe the onboard is up to it, or you could use external USB. Or maybe you want AC3 over s/pdif. Cheers, Martin.
