I convert many .flv files using SUPER to DIVX then to .wmv with RiverPast Video Cleaner. I also use .mov files in ConvertXtoDVD. I then add these files to ConvertXtoDVD and burn them to file. Once done, I use IMGBurn to build into an .iso and then use the .iso in Nero Recode to rip the video to iPod format. What happens is the converted video has Audio Pops and Stutters. When I drop an .mpg, .mpeg .divx, .xvid or an .avi, it all works. Sometimes the converted .flv may work but without a problem, same with the .mov. Its a hit and miss and its angering to no end.
