Since someone has been spamming these news groups with ads for a "free download" video converter that is NOT free to register, I thought I would add a link to a converter that IS actually free. It's just the first one I came across. Earlier today I found several references on http://lifehacker.com to several other converters, some of which had Mac and Linux versions available also. Before you go paying for a video converter that is advertised through someone enticing you with a "free download" do a quick Google, on the subject, there are many available that are actually free. I haven't tried any of these, as I do not run windows, and any video conversion I would happen to do myself would be done from a Linux command prompt, the process of which is beyond what I want to try to explain in a posting here 
(And no, I have absolutely no connection with this videora product or lifehacker.com, I just hate spammers and scammers worse than just about anything else I can think of at the moment.)
