I ripped a dvd to svcd format, in three parts..I used the same settings for all three parts. I converted the svcds to divx using vidomi (I find that's the best way to get high quality divx with incredibly small size), again using the same settings for all three. When I load up the first part in virtual dub and try to append the second avi, vd tells me "The video streams have different data formats" Is there anything I can do? Thanks
