gh22ns50 and se-s204n

hi all!
i have very big problem with my 2 dvd burners. 1 is internal and 2nd one is external.
i can burn with them whatever i want on cd-s but when im trying to burn something on dvd-s burning start (but nothing is happening) after 3-4 min burner eject dvd out and when i look on it,i can seen that the dvd is burned partially.
i`m sure 100% that both dvd burners are ok and i know (because i tryed) they work perf. on win xp.

LG gh22ns50 is sata
samsung se-s204n is usb
i have one hd samsung sata and 2nd hd wd is IDE.

in device manager both burners are shown in unknown devices,maybe is that the whole problem.
ill post picture here.
and i really hope that you will help me,this is my last hope.

if you need any other info. feel free to ask.
and sorry for my english

There are newer drivers nd firmware for your LG here: LG Product Support for GH22NS50

According to Microsoft the Samsung is compatible with no action from you, what software and version are you using to burn the DVD's?

thanx for your post,but my firmwares are updated for both dvd burners.

i tried:
nero 6,7,8,9
ashampoo 10
xpburning...
and everything els.

i am able to burn just with imgburn but even imgburn wont burn everything.....

i really dont know where to find solution.

Windows 7 has a built in ability to do this and not all of the other software is up to Windows 7 standards, I've used Windows 7 and Nero 9 and both work, if you are using generic DVD's you might want to try some 4X company named ones I've had very good luck with Memorex DVD-R media.

i tried all kinds of dvds (brands) till now.....i destroy maybe 30-40 dvds with no luck......and yes all speeds.

i can burn only simple cd (700mb)....

someone help plz

i dont know why tis forum have name "windows seven forums" .......if nobody can help.
