VirtualDubMpg2

I installed VirtualDubMpg2 on my PC running WinXP
with Windows Media Player 9 installed. Package was
unzipped into folder "C:\virtualdubmpg2" and run from
there. I downloaded binary and required dll's. No
problem loading MPEG-1 files, but attempt to load
MPEG-2 vids yields the error message:
"MPEG Import Filter: pack synchronization error".
I note that this is the same message I get if I try to load
MPEG-2 files with the vanilla version of VirtualDub. This
seems very suspicious to me. Perhaps I have not
installed the tool properly? Not knowing where else to
put them, I placed the dll's in the same folder as the
binary. Hopefully this is okay. Can you tell me what
I'm doing wrong? Thanks in advance. My email
address is joehorowitz@attbi.com. If there is a
problem, you may also use hojo-wn@worldnet.att.net.
