DVD High Compatibility Mode

[semperego]

I have many ISO files which are well under 1 GB. In as much as the configuration settings show: ISOWRITE_DVDPlusFinaliseDiscWithMinimalRadius=1 which means minimum 30 mm radius, the final DVD does not come out with a 30mm minimum radius, making it incompatible with quite a few players. Are there any other settings required or is this feature simply not working? Same ISO files burned with CDBurnerXP (high DVD compatibilty on) come out right.

That option controls a drive feature (which is obviously only for DVD+R media, not DVD-R).

 

I won't pad the end of an image with zeros because that destroys the last anchors in the UDF file system.

 

Have you actually found loads of players that the discs won't play on or are you going by what you've read somewhere? It just sounds like one of those problems that are complete rubbish.

Rubbish? You think I wasted my time to get your "rubbish" answer?

No need to get funny about it, I simply wanted to know if you've actually tried said discs in load of players (what are you doing, selling them to people?) or if you're just going by what you've read.

 

I don't see why players would *need* 1GB worth of data on a disc. Obviously I've read about the whole 30mm thing in the MMC specs (hence why the option is there) but I've never experienced it first hand or had loads of people reporting problems regarding it.

 

The players have the rubbish problem, not you.

I used to have at least half a dozen clients a year (give or take) who were returning their DVD's because they were not playing in their machine or their relatives machines. Again, these were short DVDs anywhere from 1/3 to 1/2 GB. I also have a couple of our own locations where the DVD players would not play the same disks. From my experience, the cheap built in DVD players into portable TV sets such as Ampex, Toshiba, Magnavox, Philips are likely candidates for these problems. Again, using the high DVD compatibility mode (such as the one in Nero and CDBurnerXP and others) solved the problem in almost all instances. Naturally, I have other rejects that are not associated with the 1GB limit but that is another matter. That's all the information I can provide and I thought it would be of interest.

If you're able to test a disc on a known problem player then you could mess around with the 'Image Minimum Sectors' value. A sector is 2048 bytes so you'd need to set it to 524288 to ensure the image is at least 1GB in size.

 

Of course that only applies to Build mode, not Write mode, so you'd have to actually create the ISOs with ImgBurn.

 

Out of interest, what type/format of discs are you using and what drive(s) ?

If memory serves me right, more recently we use Sony-D21-00 as DVD+R disks and Liteon IHAS 324-98, IHAS 424-98, LG GH22NP20 as drives. However we also used Taiyo Yuden, Verbatim, TDK, Ritek and who knows how many more as DVD+R, as well as Sony, Plextor, HP as drives.
