>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.

Hi Charlie,

        I have some questions about Philips SAA713x cards. 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.
