DVD/MPEG1 to M2V/MPEG2 assistance

[dronon]

Hi! I recently received a video DVD that I'd like to re-encode into M2V/Mpeg2 format on my hard drive, only I don't know what I'm dealing with any more.

The DVD had a menu and played in my computer's player just fine, but when I tried ripping it with DVDShrink, it refused and said "Invalid DVD navigation structure". So I took a look and saw that instead of Video_TS and Audio_TS folders, instead the disc had Video_TS and Video_RM folders, which I'd never seen before.

The next thing I did was copy the data manually, and then to demux it with VobEdit. When I took the resulting m2v file and opened it in VirtualDubMod, I discovered I was now only seeing about the top-left quarter of the video plus lots of artifacting. At this point, I'm not even sure what kind of video it is anymore.

When I gave it an .mpg extension and checked it in GSpot, it said it's MPEG-1, frame 352x240, SDE 720x480, DAR 4:3. When I played it in Media Player Classic, it showed at 640x480. The properties tab there gives similar information I think, only in a more confusing way.

Any idea what this is and how I can convert it to mpeg2? Software-wise to fiddle with, I've got an older version of VirtualDubMod, TMPGenc, and VideoLan.

post a sample

I can't post a sample because the original file is 3 Gig in size and I can't seem to open it properly in my editing software to cut out a clip. My editing software only gives me a quarter of the screen for some reason. (The problem may be that I don't know how to use the editing software properly.)

split it with winrar into a 1meg chunk

I don't know how to use WinRar very well; I'd need more explicit instructions. When I ask it to create floppy disk-sized chunks, and then when I try to extract a bit from just one of the chunks, it refuses, insisting on reassembling the whole and not giving me any other options.

A quick read-through seems to show that the VIDEO_RM folder is due to the use of a DVD +RW disc, and that you are stuffed as these cannot be edited on a PC

Hope that helps (but maybe not what you wanted to read)

My standalone DVD recorder creates Video_TS and Video_RM folders. DVD shrink gives "Invalid Structure" error. Then I began to use DVD Decrypter (few times) or CloneDVD (most of the time) to rip the dvd contents to hard drive and then use DVD Shrink to edit out TV commercial.

Try DVD Decrypter or CloneDVD to see for yourself

the floppy size chunks are fine - i can read them and dont need them all - just the first one ...


but as mentioned - it may be from a DVD +RW and you are fubarred

[BJ_M]

you might need to play it and capture the output - is one way

I ended up recording it to VHS and then copying it back onto the computer. Some generational loss, of course, but at this point I'd gotten fed up with this particular project. Thanks for the help and giving me the options everyone!

the video_RM folder indicates the DVD was made on DVD recorder, the 352*240 is VHS/vcd res, or EP mode on the DVD recorder

the source file could have been am input thru the A/V jacks or from the tuner or other video source

joust copy the Video_ts folder to your hard drive then use dvdshrink to re-author it,

or you can try just burning the video_ts folder to a DVD using imgburn

the video_RM folder contains data specifically used by the DVD recorder when createing the files during recording process

and are NOT needed when it comes to copying to another DVD

look around and you will see other reports of people having problems with DISCs containing video_RM folders

especially people who made the original on their DVD recorder and now want to copy it

Ripping and shrinking programs look at that folder 'read the files' and end up creating duplicate sets of VOBs, because the info pointing to the vobs in the video_ts folder , also exists in the video_rm folder
