For a low cost but great system the 2.66GHz Conroe based Dell 390s work very well. If you are only looking for a motherboard, we haven’t encountered issues with name brand vendors. Adding PCI-e card to a fast system is much more reliable than the older PCI-X days, these systems are getting easy to build.

Re: “I too would like a standalone app to capture with!”
We have the Intensity working with the Sony HVR-V1U (with 24p extraction from 60i) working through CineForm’s HDLink utility; compressing to CineForm AVIs in RT of course. This is a standalone application. Expect the update to be out soon.

It seems that the disk is limiting you to three streams. If each 60i stream averaged 15MB/s (guessing) your drive is unlikely to sustain 60MB/s necessary for four video streams and the audio data, with seeking. A second drive in RAID-0 will fix this.

Which resolution and frame rate? What is the data rate of your source files? It seems that the 78MB/s drive speed would be a straight line speed, and playing multiple video clips requires a lot of seeking for video and audio streams (which Premiere stores separately.) You can definitely do more than 3 streams on that system with the drive throughput to match.

We just got in an HP xw8400 with 3Ghz Woodcrest Xeons for test as a reference platform. The previous woodcrest system was a pre-production workstation from Intel.

If you do some testing you will find Prospect HD’s codec close enough to mathematically lossless. Plus you are capture over analog connection from a HD100, you will lose far more in the cable than you will in compression.

This month CineForm is aggressivily pricing Prospect HD to get customers into a Xena LHe card. If you already owe Aspect HD the upgrade to Prospect HD Edit is effectively free with the purchase of the LHe card through CineForm. That are several other pricing options available https://www.cineform.com/products/ProspectHD.htm#PHD_Pricing

For file based transfer (which I think is preferred for P2 camera) can be archived with CineForm’s Aspect HD or Prospect HD. All the CineForm products have been updates to support all the shoot modes of the HVX200.

A small product plug. Prospect HD will work with the AJA Xena LH with Premiere Pro, and the transitions are real-time. Yes, it is a compressed workflow vs your current uncompressed setup — they are not mutually exclusive. Forum moderator Tim Kolb is using it. Sorry Tim for outting you. 🙂 Brent, have you considered a trail?

If you going to use Xeons, get the Demspey based Xeons with the 1066Mhz FSB, the 800Mhz parts you have selected have quite a significant memory bottleneck — not great for HD. Keep out blog on the performance of the Dempsey/Glidewell Xeons (https://cineform.blogspot.com/2006/06/four-cores-more-merrier.html.)
Also you should also consider a Prospect HD + AJA Xena LH/e combination. This will get you 10-bit compressed processing, without the multigeneration issues of editing in DVCPRO-HD.
