I am convert my DVD library to .avi files to free up the clutter. I am using Avi.net to help me with the process. I have made nearly 30 successful conversions in perfect quality thus far with this program, however there are a few movies that are giving me trouble. I have a few files when I load the .VOB and it begins to preview the video it doesn't have any audio whatsoever. The option to change the audio settings is even greyed out. What do I do in this case to get it to work? Another issue I am having on other DVDs is that when it previews the loaded VOBs in Avi.net, the audio is out of sync. Keep in mind that when I play the ripped VOBs in Videolan or whatever, they play perfectly. Any suggestions?
