Quote:Then we have logical format compatibility issue(s). Probably the very ground for all the controversy around DVD+RW, rather around DVD+RW media not being playable in a whole range of players. DVD+RW Alliance was keen to blame on DVD-ROM vendors, even claiming that they deliberately block playback. But the fact is that format specifications don't explicitly say that unrecognized format [designated by "Book Type" field in "Control Data Zone" of the lead-in] should be treated as DVD-ROM and [in my opinion] it was rather naive of them to claim and expect that the media will be playable in "virtually all players." This deficiency was recognized by practically all DVD+RW vendors [well, apparently by "traditional" DVD+RW vendors and not "latest generation" vendors such as Sony, NEC, TDK...] and a secret vendor-specific command manipulating this "Book Type" field was implemented. So if you fail to mount/play DVD+RW media, you might have an option to
Once again. Not all vendors support this and you can't expect this utility to work with all recorders.
It's naturally not possible to manipulate the "Book Type" field on DVD+R media, that is not after the lead-in is written [which takes place at the moment the first session gets closed]. But it might be possible to control how it [lead-in] is going to be branded by programming the drive in advance:
dvd+rw-booktype -dvd-rom -unit+r /dev/scdN
Meaning that if you fail to play DVD+R media, you can attempt to burn another disc with more appropriate unit settings. For more background information about dvd+rw-booktype, see "Compatibility Bitsettings" article at dvdplusrw.org.
There [potentially] are other logical DVD+RW(*) format incompatibilities, but the "Book Type" issue discussed above is the only one "officially" recognized. Well, it's actually understandable as it's the only one that can be recognized and addressed by a DVD+RW vendor alone. Recognition of other incompatibilities would require cooperation from DVD[-ROM] player vendors and that's something they apparently are not willing to show referring to the fact that DVD+RW format is not approved [and apparently never will be] by DVD Forum(**).
That was greeted with silence by the "you can't bitset under linux.. you must use closed source applications run in wine" so called "experts" linux dvd burning brigade.. hahaha.. I can set my +r's to -rom on a drive with firmware which according to imgburn isn't capable of it. Just shows the real power of linux when you actually delve beneath the skin and forget the crutches of the windows mentatlty.
ps.. how do you like the samsung?.. I have one of those and it's pretty good for the money.
