i use sms 1.7rev7

when i just burn the system.cnf, sms.elf, boot.elf with NERO on CD-R
sms work, and can read my avi on my other cd-r,

but it wont read my avi on DVD-R, the disc just stop spinning.
and i try to use the "dvd-video" trick, its still not work (my ps2 can play the dummy video, but SMS still cant read the disc, the disc is spinning, but sms not read it)

then i tried burn dvd-r with system.cnf, sms.elf, boot.elf with NERO, and also my avi. and, the disc wont boot, just stop spinning.

is there a way to fix this problem??

and i think, if i can change the system.cnf LBA on DVD, maybe my PS2 will boot it, but CDGENPS2 only can make CD image, not DVD...
help...

i use PS2 slim 70006, modchip MI 1.38 (i think its a clone, maybe modbo)
