You can use more than one easily. I have this and a Hauppauge HVR 950
which is literally the same piece of hardware and I do simultaneous
recordings with both all the time.
If you record HD it requires no cpu power (~2% to write to disk
perhaps). If you record analog you need cpu power for software encoding.
So having a ton of these running all at once doing analog would
probably not be the best. If you had two running analog at once it
probably wouldn't be a problem with a modern dual core cpu. I wouldn't
buy this for the analog though - I bought it for OTA ATSC.
