I doubt it; Doom demos are simply stored sequences of mouse movements
and keypresses, so the smallest change in a map or the executable itself
may cause a demo to desync. And since ZDoom and JDoom are nearly
complete rewrites of the Doom engine (and both AFAIK use different demo
formats) it isn't possible to run old demos with them.

Now this might be possible, I even seem to remember reading of a program
that can do this. Does anyone else here remember it, or was I hallucinating?

doom2.exe is trying to access your Sound Blaster card's hardware
directly, and XP doesn't like that (neither will 2000 or NT). Especially
if you don't have a Sound Blaster-compatible card...

Fortunately, both of your problems can be solved by using prboom
(http://prboom.sf.net/), which not only runs fine in XP but also
provides compatibility modes for playing back of old demos.
