Size limitztion?

[Imlurker2]

If I string together 3 9gig movies which have a total space of 26gig, can I rebuild it to have a space of 23gig?

If so, how?

I know the rebuilt size was modifiable years back but at that time 50gig portable discs were unheard of.

:thanks:

It depends on the format. You are limited to 1GB per VOB file, and nine VOB files per VTS. So in order to do that you would need multiple VTSs each of which is no more than 9GB. If you meet that, there's no reason (I can think of) that you couldn't do it. You'd just have to change the TargetSectors value.

Thanks.

Do you have a reasonable guess as to the numbers of sectors to use for what the disc maker claims to be 25gig. It will ease the trial-n-error method.

I know I have to divide by 1024 but if one uses the 9 gig disc as an example, that becomes = a 9 gig disc is 8.5 gig with about 7.8 gig of useable space - BUT 7.8*1.024 < 8.

TIA

Using this formula:

Out_Size_In_Bytes = 2048 * TargetSectors * 1.015

So:

1GB = 1073741824 bytes, and 25GB = 26843545600 bytes

Therefore
26843545600 / 1.015 = 26446842956
26446842956 / 2048 = 12976861

A value of 12976861 would result in a 25GB output.

Be careful, though, often in disc capacities they don't call out the actual values in true GB. They consider 1 GB to be 1000000000 bytes rather than 2^30.

Thanks much.

To shrink 25 G to 24 G (to pick numbers) takes some time.
If the number was too large the result would be too large which would mean start again.

I forgot about the 2048. When I looked at an old ini I noticed right away that 2048 was the number.
