Question on Shrinking

[BurnerFreak]

I believe i am right in saying that DVDShrink doesnt fully support the ISO File system, read somewhere about a 32K chunk with a gap which isnt correct.

 

What i dont know (and cant find out) is if Recode 2 suffers from the same problem or has this bug been fixed (when you make an NRG file) ?

 

Opinions please

You could probably experiment and find out for youself.

 

To test, you need to make it so that any _0.VOB file it makes is

 

Then look at the image within ISO buster and see if the (end of the) ifo and (start of the) bup has at least 1 LBA address between them that's divisible by 16.

 

It's not a major thing and certainly nothing to do with ISO or UDF specs.

 

It's probably just advisable for DVD-Video because if the IFO and BUP are in the same ECC block and that gets ruined, there is no chance of reading either of them - making the 'BUP' file pretty pointless as its purpose in life is to be a backup!

Thanks LUK

 

Firstly how do i do this bit ?

 

To test, you need to make it so that any _0.VOB file it makes is < 32k in size.

 

Do i just compress to max ?

 

I just did one in recode and the _0.BUP is 74 K ?

 

There is no _0.VOB only _1,_2,_3,_4.VOB's but there is an _0.IFO ?

No idea how to do any of it, I've never looked at recode! lol

 

You just need to check any pair of IFO/BUP files.

If there is no VOB between them, so much the better.

If a vob is ever > 32k in size, forget about looking at that set - they will always be > 32k apart.

 

(That's because it goes _0.IFO, _0.VOB, _1.VOB, _2.VOB.... _0.BUP)
