Yep, all return values are coming back as S_OK

Yep it seems to work OK with AVI.

Thanks Joe sounds great. Be advised, one thing I noticed is that after
installing WM 9.5 Format SDK the other day, I have been getting a large
number of First Chance Exceptions being kicked out from wmvcore.dll do you
think this could have anything to do with it? Everything WMV still reports
to be working but I get lots of exceptions fly by in the debug output
window. I was on my searches that other people have had similar problems but
haev not found a way to get rid of them (I am still tackling the current
problem using DirectShow not the WMSDK). I have since uninstalled the WMSDK
and still the output exceptions keep coming :(
