I have no idea if they'll work for you.
RitekG04 works perfect for me (new or old fw 1.06 doesn't matter for me).
Getting great results with Taiyo Yuden DVD-R and DVD+R and Mitsubishi DVD-R - even at 8x speed.
Maxell DVD-R is great as well.
Even CMC DVD-R and DVD+R works good for me with this drive.
