Error in burning data only ,burns dvd-r OK

[glassrafi]

Hi
I just got the dw-U10A the (oem version of sony dru500a) firmware 1.1d
I have P4 256 XP Pro
Nero 6.0.0.9
I burned already 2 dvd on dvd-r x4 with Nero and it turns out great with no problem ( it took about 15 minutes to burn 4.5 Giga)

But when I tried to burn data with nero I did not succeed.

First I got the message "can't burn at x4" after 2% of burning
I tried than at x1 it seemed to work but after an hour I got error
On the burned dvd I saw all the files but could not display them or copy.
I ruined 3 dvd-r in the process.

what seems to be the problem ?

Should I upgrade my firmware ? is this the problem , I tried to upgrade from the firmware page to 1.1.e but it did not detect my dvd
even that DriveInfo22 did, as Sony DVD RW DW-U10A 1.1D

Any help will be appreciated
