hi everybody,
I am a holder of an old PCI hauppauge nexus dvb-s card, that has been working very well for years; unfortunately a lot of TVs satellitare is obviously changing to the HD and the DVB-s2, therefore I would buy a new card to be able to see these TVs, my intention it would be to still buy an hauppauge consider the positive experience, I have seen that the card WINTV Nova HD S2 should be suitable to my case, I wanted however to ask to you experts some suggestion, above all the differences among PCI card and external through USB, I would be more interested with inside PCIs gives me an idea of greater stability. Here is my configurations:

xp service pack2
amd athlon 64
3500+
2.21 ghz
radeon x300 hm pci-x
mboard asus a8n sli 939

the software I used it's of course progdvb
thank you
