So ... more than six months later, I can finally revel the culprit was ... 
THE C-P-U !!! <shocked gasp from the crowd />

I bought a new DVB card, and had thus replaced *everything* in the box 
except the CPU.  The lock-ups & reboots persisted.

Still not wanting to believe it to be true, I only bought a $40 2nd-hand 
core2-duo, replacing my core2-quad.

Lots of problems went away.
     Crashes (although it's only been 12 hours, so maybe I'm being too 
optimistic).
     Transcoding didn't work properly either - it missed cut points etc.
     Running a high-end open-gl screensaver (it shows my photo album while 
idle) used to lock it up

I still need to do some more testing, but *fingers crossed*, it's all fixed 
with the CPU.

Are CPU's repairable ?

I wonder if it's still under warranty ?  Don't think I have the receipt.

cheers,
