Pb with TEAC DV-W50E

[gcossiaux]

Hello,

I change my mother card and now when I burn with my TEAC DV-W50E,
the DVD IVDEO made is wrong about after le midle of the video.
With all my Video DVD. :(

I replace an ASUS Pentium III CUS-L2 by an ASUS deluxe Athlon.
My OS is the same, (same windows use)

I would like upgrade the firmware, but not suported by teac but made by Teac.

Can you help me please ?
