Osprey 210: Good?

I've been using a Canopus analog-DV converter to capture and it works
okay. Gives me frame accurate editing and so forth. As long as I
convert to a high bitrate MPEG2, the final output looks fine.

Now that I convert lots of analog material to XviD and H264, I'd like to
capture to a lossless codec instead of using DV compression for capture
just to convert to yet another compressed format. I'm sure, just as
people have advised, the final MPEG4 or H264 output will look better if I
use a lossy compressor only once.

I yearn to do some good captures to HuffYUV. Most of the Conexant 2388X
and Brooktree BT87X chips I've tried on PCI cards just aren't satisfying
me.

I've heard the ViewCast Osprey cards are good enough to satisfy the real
perfectionists. I can afford the Osprey 210. It's all I would need.
Anyone willing to share personal experiences about it's performance?

Like, DMA. It claims to do it well. True? Then there's sound and video
on the same card. Do you think the clocks are sync'd and will eliminate
audio skew problems?

Any idea what video chip it uses? Is it an Osprey propietary thing or
something from Philips, Conexant, or some other?

Anyone using an Osprey through the VirtualDub WDM Wrapper for capture in
full frame 640x480 or 720x480 to HuffYUV?

Lots of questions, I know, and I'm sorry. Any Osprey experiences you
feel like talking about will be appreciated. There's not much in the way
of performance reviews about the Osprey line on the web that I can find.

I have an older Osprey card and it's very good for .avi capture,
as the audio is locked to the video, unlike the ATI stuff. The audio
input is right on the Osprey card, along with the video. ATI relies
on your sound card for input and depending on the accuracy
of it's clock you can have sync problems.
