I am new to video conversion. I found out Virtualdub is a very good video editor. I used it for AVI files. I also installed MP4 & FLV import plugins. But when I try to import an MP4 file, I get an error.

"Unable to locate a video codec to decompress the video format 'avc1' (unknown)".

I have K-lite mega codec pack 6.0.4 installed on my Windows Xp SP3. And I can also play the file in Windows Media Player. Still can't import in VD. Maybe some settings are incorrect. Or any other problems???

Any suggestions???

My VD version is 1.9.9. Below is the file info I am trying to import in VD.
