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 zipped it and tried to transfer to my home computer with Winzip, but it came up with an error to do with compression.

Hope you can help me out here.
