Also - I bought a TV card based on Philips chipset and I can see the TV great im my PC - can I just use this kind of card?

No. They typically dont have the required hardware MPEG2 encoder, so dont work with GB-PVR.

mine has mpeg 1/2, AVI and WMV support

and I can use 4 cards in 1 PC?

Yes.

what is the limit?

There is no limit set by the application, but your machine's I/O may start have to problems with too many concurrent recordings occuring at the same time.

What kind of PC do I need?

I dont know. I havnt tried that many analog recordings at one time. It'd be a pretty safe bet to guess you need a fast machine, with a lot of memory, and good I/O system (fast disks etc).

Thats software encoding, not hardware encoding.

I have a Philips 713x BDA Analogue Capture card

Yeah, I'm fairly certain that doesnt have the required hardware encoder. If you run filtercheck.exe from the gbpvr directory, and post the filtercheck.log, I'll confirm.
