Re: how is this possible?

i'll check some of those links this afternoon, thanks! aight, here's some background on this...might help, might not...

when copying from the disc to my hd to run the specs above [james' post], i only copied the VIDEO_TS folder & not the VIDEO_RM folder...

this was from a VHS > SA recorder transfer over in Holland...no multiple titles, slideshows or audio features--just a straight transfer that clocks in around 26mins or so w/ typical SA menu and random chapter points...it arrived to us on a standard Sony single layer DVD+R

bitrate specs according to MPEGStreamclip:
Quote:
AUDIO -- AC3 2/0, 48 kHz, 256 kbps
VIDEO -- MPEG-2, 704 × 576, 4:3, 25 fps, 9.55 Mbps, upper field first



so that said, on to yer ?s:

was it 'closed' for compatibility ?
is the Video_RM folder causing the issue?
is it DVD-RAM / DVD drive transfer issue ?
i have no idea about any of the above...this wasn't transferred by us or the kid who sent it over to us to liberate, so detailed info on the transfer is unknown

Decrypter [iso setting] and reburn caused the disc to appear the normal size of 1.77GB, but the VIDEO_TS folder itself still reported as 5.22GB

2] If so, can you determine how much time it thinks it has remaining at the beginning? 3] Does the disc have three different distinct programming choices? (for instance, a main feature, a behind the scenes, some long slide-show set to music, etc) or just the main feature?
1] yes
2] shows the proper 26mins and change as its playing thru...dunno about total disc time reported before actually playing the disc, i'll check this evening
3] nope, just the main title

So basically 5.22 GB for a 30 minute video that conforms to the DVD standard is impossible, unless there are lots of bonus features w/photos or extra audio without video or something.
Maximum that system may report for a single layer R+ disc is around 4.7 GB, while real size of files that can fit to disc is 4.483 GB.

Not sure for this case but I saw many times that for standalone authored discs some programs report the contents twice, even the files are not physically doubled. However, it doesn't explain why 30 min. or 1.7 GB rises to 5.22 GB .
looks like the video bitrate is higher than normal, but not enough to account for the 1.77GB v. 5.22GB size difference...i tried demuxing/re-authoring to see if that would fix the problem and DVDSP wouldn't mess with it, said the video stream's bit rate was too high...doesn't surprise me since above 9Mbps isn't really standard

never thought of that, will try this afternoon


i'll check those links ya'll posted tonight as well, i have a feeling its a DVDRAM thing i've never seen before...but wondering if maybe James is right re: the title being "recorded" 3 times [hadn't noticed the identical file sizes til you mentioned it]...i'ma try burning just the first VTS stream and see what we get


cheers for all the help ya'll!
