All kinds of recordable media come in different revisions and standards, DVD-R aswell as DVD+RW and DVD-RAM.
The burning ability is the one side: a suitable burner which supports that specific media from the hardware side, then the specific speeds the media were rated for also by hardware and firmware.
The other side is for reading/playing them.
What we have seen (mostly in earlier days) with CD-R and CD-RW also counts here.
First the hardware must support it, at the 2nd step the firmware/software must support it.
eg. a CD-R burned too fast (data/VCD/SVCD/etc.) can be either denied by the player/hardware to be recognized, or it will play sucky, or it will work if it is supported.
Same with other recordable media, DVDÂ±R, DVDÂ±RW and DVD-RAM.
RW media is still more complicated and different (and it will stay so most likely).
There are various RW specifications/levels which are incompatible to each other... we've already seen this years ago when HS-CD-RW and US-CD-RW were introduced.
That's why I cam to this copnclusion:
If you have luck you can make your standalone/player capable to recognize/play such RW media within an firmware update. I see no other way to gain that capabilities.
As for the exact specs etc., I have to search a bit to find them... if anyone is interested.
