Hi Robert,

Yes i have my audio card and drivers all installed. I will be trying to play
MP3's, but that can't be the problem b/c the exception is being thrown just
on intitialization of the object, before it even gets passed any media!

MediaElement me = new MediaElement() ;

is the line that is throwing out the exception! It is most peculiar...

Absolutely - and that was the first thing I thought of when first
encountering the error - I wrote in my first post:

I sent a friend of mine the code, and he was able to run in without problem
- so there is definetly somethign weird going on with my system in
particular. Can I provide any information about the system or some kind of
diagnostic file that can help figure out what is going on? While this may be
an isolated case, my system setup is pretty standard run of the mill XPSP2,
..net 2.0 / vs2k5 RTM - so its possible that others may be affected with this
"hiccup" (don't want to call it a bug) as well.
