Skipping FMV's driving me mad...maybe the media?

[skykid]

I use RiDisc by Ritek DVD-R.

But the thing is it works great for movies but not so good for PS2.

I have found that the FMV's and jump, which is a shame for FMV's like Final Fantasy and Sometimes the Audio is out of Sync if it doesn't skip...which is a shame when you see bonus things on Rise To Honour or the Suffering.

I have a OEM version of DRU 530a and its called a Sony DWU-18a it got pretty good reviews.

Another thing i have noticed is that in DVDDecrypter it says that the disc can do speeds of 8x (it says 4x on the Disc) and that its dye is G05 shouldn't it be G04 for PS2?

What do you recommend i have seen a 25pack of Verbatim, for £11
