Getting burned just before the burn: general error

Question

After a bit of struggle getting CS4 on my machine, (an upgrade from CS3), I did a test project of a few short DV-based shorts and tried to burn a disk. Just after a successful transcode, it gives the "general error" error and stalls the burn. Same thing with burning a folder or an image. I also noticed that if I try to preview the project again after burning fails, it won't preview either (although it will before the burn attempt). Any attempt to bring in pre-rendered (*.mpg) files from any source hangs the whole machine.
I have taken some of the advice from the forums, like removing the audio track, etc., to see if this helps, but so far it doesn't. I am running it on Windows 7 64bit, but it has not had any issues so far with PP CS4 or any of the other Adobe products compatible with the Vista 64bit OS.
Machine stats:
Intel Q9650 cpu
Intel DG33-TL mobo
8GB memory
1TB RAID 0 for SD and HD files
nVidia Quadro 540 graphics card
No overclock or special tweaks
Been using PPro since 1.0, but have not seen this problem before.
Another perspective maybe helpful.
Thanks-

Addendum:
I have used Cineform in the past (Aspect HD) but I removed it because it was interfering with some of my other software. I replaced it with NEO player, but I'll see what taking that off will do.
I sometimes use the Blackmagic Intensity Pro for ingest of some of the HD footage into Premiere.
My machine, for reasons I cannot figure out, recognize any camcorder through Firewire (I generally use P2 cards anyway); I do not think this bears on this particular problem with Encore CS4.
