Hi... I have a Panasonic DMR-E50 DVD recorder, and I occasionally copy the
..vro file to my PC via an internal DVD-RAM drive for editing and burning to
DVD. But I'm thinking of getting away from DVD-RAM, and wondering what file
structures other DVD recorders use. Do any of them create standard DVD .vob
file structures? I have searched extensively for this information but
haven't
found any.

I regularly use DVD-RAM for editing on the computer and find the other
alternatives inferior to this method. Why are you not happy?

Hello,

I own a Panasonic E65 myself and so must use dvd-ram's too in order to
edit on my pc. In what respect is editing dvd-rams superior to editing
on dvd-rw's? I am very curious to know!

I thought is would be simpler to copy VOB files from any of my DVD drives
under any OS. Also the RAM drive takes up a space I rather have another
drive in.

And I cannot read the DVD RAM files on my Windows 98 computer, which is a
back-up computer I wanted to use mostly for editing. Haven't found an answer
to that in much searching.

Works fine on my XP computer.

I currently use DVD Author, and VRO files don't even appear on their list of
video files to open - have to use "All Files" setting. And I sometimes get
problems like sections of the video dropping down to half-width when
editing, resulting in errors.

If I play the VRO file in a DVD viewer, it's normal - but not always in DVD
Author.

Could be my recorder is having problems, or I need another editor. But I've
found most of the other editors I've tried are inscrutable compared to the
simplicity of DVD Author.

Mostly I'm using my recorder to save classic movies and documentaries off
cable, and portions of home-improvement shows.

Thanks for the replies.

I don't use DVD-Ram but I think you should use the button called "Add
DVD Video" instead of trying to add the files. What I understand,
TMPGEnc DVD Author (TDA) can read the format from DVD-Ram also.

I use DVD+RW and reading individual .vob files is not a good idea.
With the "Add DVD Video" function, TDA lets you pick the Title from
the disc that you want to import. (One Title might use use several
vob files.)

I use TDA version 1.6 to give me one single .mgp file from each
import, which I can use in other programs with file import.

(I have a sound drop out issue with both TDA Pro and TMPGEnc MPEG
Editor if I import directly from DVD+RW disc and they don't give one
single .mpg file so I do all imports with TDA v1.6.)


Try the above method and see if it makes a difference.

For one I find the RAM disks last much longer than RW. That is not my
main focus, however, which is sync problems between the video and
audio. The problem I found with editing vob files has to do with
the structure of the files and the way a dvd is played back.

VOB files consist of a series of records [2048 bytes long] with
headers identifying the records as video, sound, navigation, and
other types. Each record contains the SCR, system clock reference,
that allows the player to sync its internal clock to the clock
used to generate the dvd. In addition to the SCR, the audio and
video records contain another time stamp: the PTS: presentation
time stamp, the time at which that record is supposed to play.

For example, you might get a record with SCR=1hr:12m:32.4 second
and a PTS=1hr:12m:35.4 seconds, which means that record is to
be played 3 seconds after it has been read. The player buffers
that record while playing whatever material had already been in
the buffer. When the SCR reaches the corresponding PTS that record
will start playing.

When you chop out a chunk of a vob the player doesn't have its
buffers full of the material that preceded your cut. It happens,
too often for me, that some recorded material either plays back
haltingly or exhibits ridiculous lip sync problems. The VRO
format generates audio/video records with very little difference
in the time stamps and I have never had playback problems after
editing RAM files.

Make sure your drive can read RAM disks. The Pioneer drives can.

I am not familiar with DVD Author running under Windows but on the off-chance
that it is a ported version of that running under Linux, you might look
at the DOOM9 site, under "Linux and other OS's" for a utility that will convert
VRO files into pseudo-vob files that are acceptable to the authoring program.
Also note that an update fix for that converter was published in the same forum.

I'm using XP.

Here is a link to a snapshot of the problem I am having:
http://www.cox-internet.com/kenb2002/vro.jpg

I have to open as a file, not DVD. When I try to open as DVD I get "mixed
video format" error.

I have removed TDA and re-installed, with same results.

Sounds to me that TDA is telling the truth.

Is it possible to change horisontal resolution (recording quality)
within one title on your recorder?
Is that what you have done?
If so, can you split the clips having different resolution into
separate titles on the recorder before you import to TDA?

I've found something in a forum post that might solve the problem...changing
a video setting from "Automatic" to "Fixed" in the Hybrid VBR Resolution
section. Time will tell.

Thanks for the responses.

Then copy the VRO file from the DVD-RAM to your hard drive...rename to
MPG.....POOF!

Changing the recorder's video setting seems to have worked. A vro video
loaded into TDA this morning worked out fine.

Yes, that's a well known fact...

This I think is a very interesting story!

That is good to know. I have always been eager to know in what respect
dvd-ram is superior to dvd-rw, except for during much longer of
course. However I must say that dvd-ram's are much less cheap as
dvd-rw's and I have had all sorts of little problmes with using
dvd-ram. For exemple you should be able to format them as FAT32 and
then use them as kind of harddisc. This is hardly true as with great
pain and costing much time i only succeeded to format in Fat32 two of
my 14 dvd-ram's. I had to use ReadDvd! from SAI before I could
actually work with dvd-ram's under WinXP, etc.
