Won,t burn disc - RCA DRC8030N

when burning a disc make sure the box is ticked to play on all formats and burn at the lowest speed for better results

What burning software/version are you using?

Have you looked at this from ACER: http://acer--uk.custhelp.com/app/answers/detail/a_id/3410/~/error-code-0x207-shows-during-recovery-dvd-creation I'm sure you already know it seems to be a common problem. Every post seems to point to Media type , can't use RW disk, +or-, seems kink of finicky which seems odd. Only use DVD+R or DVD-R.

What's the program you are using?
You can try burn your disc on PC with a professional DVD/Blu-ray burning program, it should be more promising. And you don't have to manually finalize the disc.

It sounds like you are trying to burn too much data onto the disk. If you want to test this theory, you can burn a small amount of data to a blank CD-R to see if it works. If it does then you do not have a hardware problem. This will be good news.
There are different sizes of CD-R media, 650MB, 700MB and larger sometimes. If you select 700MB and try to burn to a 650MB media disk, the drive will just spit out the blank disk so as not to ruin it for a future burn. Also, if you are going to make a multi-session disk (or you have accidentally selected multi session, then you will automatically waste 22 MB leaving you 650-22 /628 MB, or 700-22 or 668 MB of space to burn your data. Each additional session will also take up 22 MB of space.
There is also a chance that the media you are trying to burn to is not compatible. Some lower end brands do not use enough reflective material for some burners. You can test this theory by trying an alternate brand of media.

format data coded not supported
convert it through a converter software . eg,XVID TO VOB.EXE or MPEG it will work

the problem normally occurs when the lens is becoming weak and the ROM is old. It sometimes does not burn correctly.The best solution is to replace the ROM
