>From the manufacturer's product webpage, it's hard to tell that the card is saa713x-based, bt878-based, or cx88-based. You have to check the CARDLIST or call in to find it out. Either for "real-time MPEG-4/2/1 encoding", without looking at the card physically or call in to check out, it's hard to say that the encoding is done by HW or SW. All claim "real-time MPEG 4/2/1 encoding", but some of them are done by HW while some of them are done by SW with their "real-time" definition like by KWorld (I bought a KWorld cx88-based PCI capture card a year ago for home use, although it only has a CX23880 on the card, it claims "real-time MPEG-4/2/1 encoding"; Obviously, it asks CPU SW to do encoding). If it's done by SW, a fast computer, for sure, is required. Otherwise, the "real-time encoding" can not be accomplished. I never tried two cards you mentioned. But, if you are looking for a HW MPEG-4/2/1 encoding solution, you can not get it cheap. Also, it may not be supported by V4L simply.

I am looking for a cheep card, and I found KWORLD Studio TV Terminator http://www.kworldcomputer.com/product/analog/002/pvr-tv7131.htm High resolution and quality is what I want: - 720x576 - 98.000 kbps for MPEG2 or about 1.000 kbps for MPEG4 and my computer is not very fast: 700 MHz. Looking KWORLD Studio TV Terminator features I see "Real-Time MPEG 4/2/1 Encoding" but I don't understand if it work by software or by hardware. Can you explain it a little more? Do this card get better performance than Hauppauge WinTV? Thanks a lot. El mié, 07-03-2007 a las 12:11 -0800, Charlie Liu escribió: > You better pick a Philips SAA713x based grabbing board.
