I have successfully used DVD Decrrpter to rip the VOB files to my Hard Drive (There are seven of them, all around 100Mb). I've then used VDub to convert them to AVI using the same settings for all of them. But how do I merge them together to have one AVI file of about 700Mb (so that it will fit on on CD). I've tried using the append AVI feature in VDub, but I get a message saying that the Video Bitrates are different. I have used Ulead Video studio, which seems to work, but it seems to put in artifacts into the outputting render (they are not there in the original AVI files).
