(CCing the mailing list also.) If the card works with tvtime, then it is probably not a hardware MPEG card. What chipset does it use? If it's a bt8x8 (848, 878, could also be labelled as a Conexant 848 or 878), or it is a Conexant 2388x, then it's a software card. Another way to tell is if you're using the bttv driver.
You didn't say whether the 700MHz machine is a frontend only, or a combination frontend/backend. I'll have to assume the latter. (If it is a frontend only, then you might have other problems.) A 700MHz machine is not enough unless you're using an MPEG-2 hardware capture card. On the playback as well, 700MHz is pushing it unless you're using XvMC. I have a 1GHz VIA that will peg the CPU at around 90% if I don't use XvMC, but with XvMC, it sits at around 40%. (I don't use the VIA anymore though, I was having a ton of problems with it). XvMC won't work with non MPEG-2 recordings, so if you want to use it, you'll have to get a hardware MPEG-2 card (or transcode everything to MPEG-2 before playing it) -- Joe --- Scott Simpson <[EMAIL PROTECTED]> wrote: > It is a 700 MHz VIA motherboard which I think should > be fast enough since > the AverTV Studio card is doing the encoding.
