I have a friend who has been using a FAST (Now Pinnacle) Liquid Silver system for some time, and the aging P3-based Windows NT4 computer finally died. He bought a new computer, dual 3GHz Xeons, 2GB memory, 146GB U320 SCSI drives hardware-striped with Adaptec HostRaid card, but the Liquid Silver codec and DV (firewire) cards will not function in the new motherboard (SuperMicro X5DA8). When trying to capture any video, the "logging tool" just simply hangs the machine, requiring you to go into Windows Task Manager and kill the "Not Responding" processes. The Liquid Silver 2.55 and 4.2 software installs just fine onto the machine under either Windows 2000 or XP Pro, but will not capture any video at all. Pinnacle is not being much help in assisting with solving the problem with his new computer, they only seem interested in selling him a whole turnkey computer only, at a price many thousands of dollars higher. We think maybe that his "codec" + firewire cards (a joined pair of cards side-by-side) are just simply too old to function in a modern machine.
We need advice on possibly a complete replacement of the video capture hardware and NLE editing software package to go along with this modern computer hardware. His primary source of video for this system is a Sony DV-CAM tape machine and he'd like to continue using it as the video source and be able to dump straight from the tape machine digitally via the firewire connection right into the computer like he was used to with the old Liquid Silver system, and be able to do all the same kinds of fancy computer editing functions and then to burn the final edited videos straight to DVD disks, which is what most of his customers want (wedding videos).
I know it's considered bad form to follow-up directly on your own question posted, but after doing a little research it seems that what we really need is Pinnacle's "Liquid Edition 5.5" non-PRO version of the software-based NLE/capture system that just uses a plain old ordinary Windows OHCI-compatible 1394 firewire card to communicate with the DV-CAM tape machine. The learning curve of switching from Liquid Silver to Liquid Edition should not be very steep, since Edition's user interface is largely derived from the old Silver product. Since my friend rarely has need to bring in video/audio from analog sources, it looks like we can totally ditch the cantankerous old Silver's proprietary wierdo hardware capture and codec processor cards and be completely free of their curse in this new hotrod dual Xeon machine.
