Cheap alternative way to record component from HD cameras at DVinfo.net

This is not uncompressed at yet, but around similar resolution and compression ratio of DVCProHD:

I am wondering if it is possible to use this to record the live uncompressed component output of D3/component/HDMI (through converters) into a more compression stable HD DV codec.

These sorts of cards tend to come from a reference design, with duplicates made by a number of different manufacturers. So the following is interesting. I have heard that the 50i version of DVCPROHD does 1440*1080i, if there is a 50i version of the card from another manufacturer with that resolution, then you will get a clean version of what your PAL market HDV1080i camera is recording at normal resolution. This would be good for Indies, as it transfers to 25p which can be slowed to 24p. Motion artifacts will be reduced to a minimum. If a version supported 720p recording even better. There maybe even a USB/firewire version for laptop use somewhere. My interest is getting a Sony/JVC HDV camera, or new H264 cameras coming (even the Sanyo Mpeg4) and recording from them.

The following are information on this product and the previous one, links to the original Japanese version is at the top of the page:

The pages are in Japanese, so the above is about all I can determine, if anybody knows Japanese and can interpret it would be great.

So does anybody know anything about cards like this, or links to other ones? There might be other cards that do the same with better compression schemes, or resolution.

I have just looked at their website again, they have posted some new information. It looks like 88mb/s, at 30-40GB per hour, with maybe 1440 horizontal resolution:

Codec information:

I can not follow this exactly, but anybody that knows the technical aspect, or knows Japanese, could probably get more out of this.

Thanks

seems it is the perfect companion to capture JVC HD1/10 directly from its D4 plug. unfortunately it cames 2 years late...
