I got a magic2 V7 console I dont know about this DVD9 business
But from FIRST HAND EXPERIENCE dvd films do skip in ps2 mode
So from standby mode(with the film already in) like the lads already said HOLD reset until the Blue LED comes on then your away.
REMEMBER if you have a MAGIC2 Chip use the PS1 boot method on DVD films to get rid of the awful skipping !!!!!!!!
