converting VOB to DIVX format?

[siluet]

what is purpose converting VOB to DIVX format? Since VOB files, once ripped, can be played back with any software-DVD player like Media Player Classic, and have better quality.

If you don't want to do it yourself, then don't. Many people like to compress movies to a much smaller size, even if it means lower quality.

Divx/xvid, when encoded properly, will give you nice looking movies at a fraction of the space needed for DVD. That is all, really. I only use it when going on trips with my little Philips portable player. I can cram several xvid-encoded movies onto a single data DVD, thus having to carry fewer discs with me than I would with standard DVDs. Some people like to create their own types of media systems, storing many movies onto a single hard drive where they can call up a title (like a video jukebox). You can get a whole lot more movies onto the drive with divx or xvid. Because this format is so highly compressed, I suppose it can be more susceptible to errors than VOB files. So, if you don't need it, don't use it.

Like filmboss80 say mpeg4 is much more efficient codec than mpeg2, but since it came after mpeg2 was accepted by all as DVD standard, it is still second fiddle. Quality is same.

so encoding already ripped VOB files to DivX make no sence due quality deterioration, errors, etc?

As filmboss80 says - It only makes sense if you want to reduce the filesize. If have lots of disk space just leave the VOB's - that's a perfect copy with menus & extras.

It offers better compression than MPEG2 (e.g. If you had a blu-ray source and made a DVD out of MPEG2 vs. the same filesize/bitrate out of XviD - the XviD one will have better quality)

It is a lossy format, so any transcoding will degrade the quality, but if you use high quality settings, it might not be noticeable
