Why does DVD2Onex sometimes make VIDEO_TS too big?

5% of the time I find that the resulting VIDEO_TS folder is slightly too big for Toast to burn...

The default file size in DVD2One is a theoretical maximum that will fit on a single layer DVD. Differences in media and the compression may lead to a file that is just a little bit too big. Actually, a recommendation from the DVD2One Forum Moderators was that the file size should be set smaller so as to ensure that you don’t write all the way out to the edge of the DVD (DVD drives write from the center outward). It was their opinion that the edge presents the greatest risk for failure, and reducing file size below the default wouldn’t have much of an effect on video quality. I have DVD2One set at User defined 4321 instead of the default 4472.

Because transcoders are not perfect.
Going about 4350-4400 is better than 4472 default.

I use mine at 4440 and keep it on Variable and have had no problems.

I use variable on most with a user default setting of 4300.
Never burns to the edge, and if I remove all extras
and do movie only, I get zero problems.

If I do DISC COPY,
then i make sure to cut out any extra Languages,
with a default 4300. Towards the end of the disc I get
some "pops" on occasion in the stream, but otherwise
its perfect.

Another alternative (I have not had any problems with) is to burn with Popcorn...Popcorn will, if the file is too large, performed the necessary compression prior to burning the disc. I try only to use Toast to burn DVD-R's if Popcorn cannot handle the file I'm burning (only happened 2x in 117 burns)...
Also, are you doing 'full disc copy' or 'movie only'...
If you are doing 'movie only' you can have DVD2oneX remove unwanted languages and subtitles which will reduce your resulting file size.
I have fit 6.5-7.5 GB files onto a Standard 4.7GB DVD-R with no noticible loss in quality.
Hope that helps...later...
