Requires software encoding, so > your P2/450 is a bit underpowered. that's exactly what i was afraid of; however, i did ask the sales person whether the card did onboard mpeg2 encoding before i bought it at worst buy and the sales person said yes it did. oh well, i guess i can always use it as another recording source. i assume that if i get a faster cpu, the video recorded from this card will be acceptable. is that true? > If you get a PVR-350, you don't need a video card with TV > out.
