Can't play titles that were split into multiples .vob = 1GB

I am doing a serie of dvds for the company I work for,
The dvds that don't contain titles with vob files that has been split into 1GB chunks play fine.
I have dvds that have small titles <1GB and 1 big title : 2x1GB file + another smaller one
the dvd starts to play but when I try to play the big title it fails, unreadable dvd.
Strangely the DVD plays fine in my toshiba home player, but not on the PCs , we tried it with powerdvd, windvd, and a few other players.
If I try to copy the 1GB files from the dvds onto my HD it fails too.

If I try to burn the authored VIDEO_TS directory using Nero
it complains about "FILE SIZE IS NOT A MULTIPLE of a logical block size" 2KB

I've seen a few older threads about that kind of problem but didn't see any solutions proposed so far.
Any ideas ?
thanks

A few more infos if it can help:

Playing the .IFO from the hard drive directly works.

Burning with a recent version of nero and ignoring the FILE SIZE IS NOT A MULTIPLE of a logical block size" error creates a working dvd. (I only got the demo version though , so I've like to be able to burn with DVD-A )
Burning with DVD-A gives the problem.
Burning under linux with dvdrecord gives the same problem.

It seems it's a problem with the 1GB files and the way DVD-A, dvd-record and older recordeing software burn them ..

Microsoft says:

"UDF uses a 32-bit integer as the size of an extent, the top two bits of which are reserved, so there is a maximum extent size of 2^30 - 1. MPEG2 data is normally written a block at a time, and this means that the block size is 2^30 (or 1GB-2KB). Because of this, if the .vob file size is greater than or equal to 1,073,741,824 bytes (the block size), the .vob file is not playable. "

This maximum size is exactly what DVDA created for me... :-( Bugger...

Yes, the splitted VOB's that DVDA creates are too big! I tried working around the problem by using IFOEDIT, and managed to re-divide the VOBs so that the large one was 1,073,569,792 bytes instead of the critical 1,073,741,824. As a result the project burned in Nero for the first time without any complaints or problems!

Be very careful complaining about this problem, the last time I did I was warned by Sony that piracy is illegal, the cops might come barging in with a search warrant and sieze every PC in the place.

Or possibly that if I tried another tack (such as using IFOEDIT) the PC might explode in 1000 foot fireball.

Seems an odd response to someone trying to duplicate their own DVDs for release. Of course you could use a program like RecordNow except we've also been warned that installing that on the same PC as DVDA may cause DVDA not to work correclty. Pretty odd as it's supplied with Sony DVD burners.

Piracy??? It's not a ripped movie, it's a 40-minute concert we've mixed! Sent the final DVD for duplication today. Anyway, got your point... I'll stick to the opinion that this is a nasty bug that needs to be fixed urgently, too much trouble working around it like this for my next project, a 90 minute concert.
