Too slow or what?

[spl]

I have a amd t-bird 900Mhz, raid-motherbord with 1 IBM 20gb dma66 7200rpm hd, 256mb sdram and Gainward GF2 mx400 VIVO. Frames are dropping like hell in Virtualdub, I wonder why? Tried different resolutions, compresson quality and almost everyting I could think of.

Harddrive reads 17mb/s writes 17mb/s. Anyway I am gonna buy a new drive soon, need more space.

Is it still too slow or what? Please help!!!

You should not have any problems with that setup.
I only have:
Celeron 600Mhz
320mb ram
20Gb 5400rpm HD
Pctv rave capture card.
I can capture at 768x576 - 25fps - Pic video codec (quality 19) with no dropped frames when I capture with Avi_io.

I have:

p2-550
128meg
aiw-128/32 set to 480x480, 2.9kbiterate, me=22
4gb os hd
20meg x2 hd and 34meg hd in pull-out caddies for captures.

it captures pretty well.

Have you checked the DMA box for the drive itself. I was getting 4mb/s out of a drive that should do around 15mb/s - the DMA was not checked. When I checked the box - whoooosh!

Well, the I have a RAID controller on the motherboard and becorse of that the drive it self dosen´t have that dma checkbox like you have. The dma setting of the drive is managed by the contoller and its set to be dma. So it should on. I tested the drive several times and the result was between 10-16mb/s for D partition were I capture. C partition had low numbers 4-10mb/s.

spl,
Have you solved the problem with that Cardexpert setup? I'm looking to build a system and like the reviews about the cards display qualities. Moderately overclocked its numbers are close to GeForce2 Pro/GTS cards. I haven't found any info on its capture quality. Other than the frame drops you're talking about how is the quality of the pics? Also, have you tried the hardware MPEG1/2 coding?

Haven´t solved the problem yet. Working on the mpeg2 capturing right now and have to say that it has its own problems. Mpeg2 cap quality isn´t as good as avi and the mpeg2 cap software that comes with the card has some sync problems with audio and video. Sound drops out in long mpeg recording that i´ve done so far and invalid mpeg files. I think that a standalone capturing card with hardware compresson would be the best way to capture. You also need a powerfull PC to capture any mpeg´s. At this point I don´t recommend this card.

Thanks spl, I'll take your (and a couple other people's) word for it on this one.
