Any guide on DIF4U's DVDcalc?

[leeza]

I have searched the forum but I cannot find any guide on DVDcalc.
Call me stupid, but I cannot figure out how to use built-in DVDcalc.

I often demux my DVDs by vobid (fixed bitrate for extras) and the bitrate caclulated in ccedata.txt is not always accurate.

If I can figure out how to use DIF4U's built-in calc, maybe I can get more accurate bitrates.

Any help is really appreciated.

leeza,

could you please provide additional details as to the problems you are having in regards to bitrate and vobid demux.

as far as i know, dif4u uses the same calculations that would be obtained using DVD Calc.

out of interest, what size have you set for DVD-R size in the DVD Calc window?

Well, I re-encoded menus with NuMenu4U and copied to VIDEO_TS folder in demux dir. I then demuxed by vobid using DIF4U to the demux dir.
I used Scenaid and batchCCE to encode videos. I imported the script and compiled and the resulting DVD falls short of DVD-R capacity by few hundred megs. I set the DVD-R size to 4700000000 (safe) in DVDCalc.

In DVDCalc, I know I have to enter VIDEO_TS dir minus main VOBs, Location of Assetes(this is where main movie is demuxed). However, I can't figure out what to enter in "Size of 1ch, 2ch, 6ch, DTS", Num of tracks, include in check boxes(what to check and not to check), Size of, Video minutes.

Apart from what to enter in those filed in DVDCalc, bitrates given when demuxed by vobid are much less than those that come close the size of DVD-R.
