my query is such

I have Virtual Dub on my work computer & at home, version 1.4.7

On my home computer I use Video Codec Version 4.1.00.3920 (Low-Motion codec) when compressing files with virtual dub

On my work computer this codec is not listed in the Compression codecs

I have copied and then downloaded this fromDivX MPEG4 Hi-Res Video Codec
3.11alpha release , onto the work computer but it still does not show up.

I captured a video and compressed on the work computer with MPG 4 Video Codec V1, then copied onto disc and tried to play on my home computer , but it came up with an error "avi file does not have a movie data block"

Hope you can help me out here.
