Sound, no picture
 

I recently downloaded a movie AVI file which Bitzi identified as the best.

When I converted it to DVD Windows media player opened but I only had the soundtrack & no pics.

I then downloaded a different file of the same movie which plays superbly on PC as an AVI but when I try to convert it to DVD I get an error message that says Cannot convert this file, maybe the file is broken or the relevant codec is not installed.
Any help much appreciated thank you.

Try installing the VLC media player, it has all the codecs pre-installed and can play just about all files...
VLC media player - Overview

or for WMP
Get one of these pacs also...
For XP this codec pac is very good
Download XP Codec Pack 2.0.8 - XP Codec Pack is one of the most complete codec pack
Or for Vista this pac
Vista Codec Package v4.5.7 (freeware)
