I use either avidemux or wondershare. wmm also plays audio and visual out of track, which is annoying to say the least.avidemux is freeware and you can download it from http://avidemux.berlios.de/download.html2.4 final install windows sourceforge worked for me.wondershare costs $39 and is from http://www.wondershare.com/multimedia/dvd-ripper/buy-dvd-ripper-platinum.htmlyou need to use this one in conjunction with dvd ripper software. it is only really used for blokeipulating dvd media.
