Occasionally I've struggled in my attempts to edit VOB files. Normally, I've simply changed the file extension from VOB to MPG and edited the file and it has worked well. However, once in a while I find a VOB file that won't cooperate. The problem files seem erratic. The problem VOB can take a long time to load, freeze the editing application, or apparently contain snippets of video that actually reside in other VOB files on the DVD.
I've done a lot of searching regarding the difference between VOB & MPEG files and it seems that the VOB contains "file offsets and time duration of all chapters" that the MPEG file doesn't include. I won't claim to fully understand the difference. However, I've been looking for a program that will convert VOB files to true MPEG files (without all this extra data) and will do so without re-encoding. I've seen and tried a few programs that have been recommended in other posts (MPEG2Cut, DVD Decrypter, YASA VOB to MPEG Converter and others). The programs that I have tried either freeze when some VOB files are loaded or they split VOB files into smaller VOB files or they re-encode the VOB and reduce the video quality. Some will only convert the VOB file to lower quality SVCD formats.
Therefore, can anyone recommend a good program that will convert VOB files to true MPEG files and leave the frame rate the same as the original (i.e. will not re-encode). I'd prefer freeware but am willing to pay for a good program that works.
Thank-you in advance
