I received my wedding video on a DVD from my videographers. I thought the picture looked a little grainy in some spots, so I popped it in my PC to see what type of file it is. It appears it's a VOB file. Is there some way to determine whether or not this file was compressed before being burned to the DVD, resulting in a loss of quality? Is there anything I should know about a VOB file? Also, I wanted to upload the file to my SkyDrive, but it won't upload for some reason. My assumption was that this is because SkyDrive might not support VOB files. So I went in to DVDFab to strip it from the DVD and convert it to an MP4. I noticed DVDFab lists the file type as MPEG2. Why would DVDFab show MPEG2 but the file itself when viewed from the DVD shows as a VOB file? I paid alot of money for their services and want to make sure I'm being provided with a high quality video. I appreciate ANY help you can provide. Thanks!
