Thanks VERY much!!!!!!
Wooow .... Thank you very much It worked
Thanks VERY much!
Worked, awesome!
I followed the instruction given by 'anonymous' but still stuck. I opened the VFW configuration from the start menu and it was set to libavcodec by default. but the vdub is again showing the same problem.
Thanks very much to anonymous. Now virtual dub is working perfectly.
