DVD-R Movies on PS2?

[Joe Forster/STA]

And will you be able to read CD's/DVD's, written at highest speed with a (low or high quality, does it matter?) CD/DVD burner, on an old and/or low quality CD/DVD reader, such as that of the PS2 or that of a neighbor/friend with an older PC? You see, I'm having major problems with reading anything off high quality TDK CD-RW's, written at 10x speed (the only speed possible) with a high quality Plextor PX-320A, on my PS2 (modded with DMS4 Pro)... But no problems with TDK CD-R's written at 4x speed! (I didn't want to waste CD-R's, for the purpose of high speed quality tests of write-once media...)
