convert it to a different format. try this http://www.download.com/Any-Video-Converter/3000-2194_4-10661456.html
still cant create a DVD with them tho....
.avi file is not valid or corrupted... lame!
I use "Convert X to DVD".
Pretty simple to use. Drag n drop hit convert button.
Convert X to DVD FTMFW!!!
hell yeah! this is what I use too, it works great! it takes a little bit, but usually just burn one during the night when i'm not using the computer since it slows it down a lot.
but like i said, this program is prob one of the best, it'll make it so the DVD will play on any DVD player too, it will also convert pretty much any video file format, so far i'm on my 4th hundred pack of DVD's and haven't had a problem yet!
post if you have any questions about it!
