Since no one on staff has responded yet, I'll offer my thoughts.
Since VRD is disk I/O bound, you need to make sure all the drives are running in Ultra-DMA mode (not PIO). You should also read from one drive and write to a second physical drive for best performance. You should check the cluster size on the drives also. 4k is default, bigger is better for video, and 512 bytes indicates a need to start over, repartition, and reformat.
With your processing power, trying to read from and write back to the same drive is going to be a real bottleneck.
Of course, there is also a setting in the "Enhanced Features" options to "Reduce CPU Priority While Saving" you could try too. I don't know if that is likely to help in your case, however.

It may be your antivirus software bringing your system to its knees. I disabled norton antivirus from reading my .tivo files because it was making my file open times unreasonable.

Some more ideas.
The machine itself is running really well other than this one glitch which may just be the drives in the wrong mode.
Vista went through redetecting all of the hardware when it came back up (I made sure to uninstall all of the old drivers first).
It slowed things down a bit but not to the same crawl that it had been at even though Im doing this on my OS disk. Things are much slower but Im guessing they should be since my OS disk is now tied up doing a 4.5Gig copy although I didn't have nearly the same slowdown when I copy a 4.5GB file via explorer.

Take the Hal or system registery, there is two very good reasons. To start afresh with a new os install.
Have done the same, had problems which manifested in time. Ended up with a fresh os install, never looked back. Ok it was years ago, but ms os's are just the same. Ok vista is different, ms will still advise the same procedure.

Create a short video file, preferably standard def, of about 1 min in duration. Then open the file in VRD and resave it. On the output complete dialog screen what are (a) frames / second and (b) average bit rate.
Repeat a 2nd time and let us know the results. We can then compare with our own machines here.

Sounds good and I think I may have found something slowing my system down. My nice highspeed SATA drive is running in IDE mode because I hadn't turned the AHCI bios on on the motherboard. I will play with that tonight.
Just tried this on my Q6600, 1 min mpeg pal dvb recording,
First run;
Video output frames: 1500
Audio output frames: 2501
Processing time (secs): 1
Processed frames/sec: 1313.49
Actual Video Bitrate: 4.50 Mbps
Second run;
Video output frames: 1500
Audio output frames: 2501
Processing time (secs): 1
Processed frames/sec: 1296.46
Actual Video Bitrate: 4.50 Mbps

When I added a SATA storage drive (motherboard controller) to go with my IDE drives, I had to install the RAID software even though I was not running in RAID configuration to get the speed up to normal.
