Betreff: [linux-dvb] Buying new DVB-T card, choice of two. Is either better?
> I'm about to add 2-3 tuners to my PC that's to become a MythTV backend.
> My Twinhan VP3021 card has failed so I'm not getting another one of them.

> My choice is:
> Compro DVB-T200
> Hauppauge NOVA-T PCI
> Both the same price, the DVB-T200 has more inputs and HDTV support
> Any particular reasons to choose one over the other?
> Does either have a better (more sensitive) tuner?
> Another question:
> As USB tuners are outside the case, will they perform better (higner
> strength, lower SNR) than PCI ones?
> If so, are they hard to set up? How many can you have hanging off of the
> USB2 before you saturate it?
> How many DVB-T tuners would saturate the PCI bus?
Some general responses:
1. Up to 4 adapters are supported by Linux
2. Please see www.bttv-gallery.org
3. Please see the CARDLIST.bttv
"As USB tuners are outside the case, will they perform better (higner
> strength, lower SNR) than PCI ones?"
I do not think so. No idea. Ask Markus Rechberger please.
SNR and signal strength do not depend on the bus type the devices are connected as far as I know......
Apart from that I am working on a script / app with which you can optimize all DVB-T and DVB-S services of whatever kind - with only ONE CARD IN YOUR PC.
In so far the assumption (and thus the software architecture of apps like MYTHTV and VDR) is rather oldfashioned, conservative, if not to say: Utmost reactionary!
Hope I could help you a bit further on.
