Cleaning up a Noisy DVD

[Sliztzan]

I would like to clean up the noise on a few older DVDs I have that weren't mastered or transferred very well.

I know how to clean up the noise with Tmpgenc Xpress.... but how can I do this with VOB files without having to convert them to mpg. I've not seen a program where the final result will be a VOB file.

I've heard some say you can just rename the mpg to vob, but other say that is wrong.

I want to be able to clean up the noisy vobs and replace the ones on the original DVD and keep original menus.

Please someone help me with this. Thank you.

Renaming vob to mpg to vob ... never going to happen ... its usual for some programs to be tricked into opening vobs for editing

But audio is done separately and must be remuxed with the video data stream after for vob

I would demux the the content to elementary streams using DGIndex. I would then load the mpeg stream into either virtualdub or use an avisynth script (personally, I would use avisynth, but virtualdub is easier) and a combination of filters to remove the noise and sharpen up the image (and any other adjustments that are required) then encode back to mpeg-2. Finally I would re-author using the original audio and burn with Imgburn to a blank DVD.

if you do this carefully, you should be able to use VOBBlanker to replace the original VOBs with the new ones. However this will only work correctly where the titleset contains only one title (e.g. the main movie titleset), and doesn't work well if you have a lot of titles in the titleset (e.g. an titleset full of extras)

I'd use xvid4psp and use the filter "tv molotov", works for me.

You can do this with Vobblanker.
See the guides here
And particularly this one.

You do have to convert to MPEG then back to VOB.

It's true you can sometimes treat a VOB like an MPEG, but not vice-versa. Once you do anything to it, it won't have the VOB structure any more and you won't make a playable DVD. So don't try to take that shortcut.

But are the menus really that wonderful? It's a lot easier to just reauthor (eg, with GfD) than dismantling and reassembling the original structure.
