Tips on Converting VOB Videos to AVI on Mac OS X

Description
As we know, VOB (Video Object) is a container format in DVD-Video media, which is based on MPEG-2 program stream format. VOB files are a very strict subset of the MPEG program stream standard. While all VOB files are MPEG program streams, not all MPEG program streams comply with the definition for a VOB file. And in most cases, you may want to Convert VOB files to other video formats (AVI, MOV, MP4 or MKV) for the portable players like Xbox, iPod Touch, iPhone and iPad on your Mac.
