As I said, I have watched media on CD's using older iBooks. Infact, the first gen iBooks. I had no issue, this is the only reason I blame the burn. Has nothing to do with hardware quality.
EDIT: Case in point, I have an .rm of a full length anime fansub. I have watched it on my comp, and my friend's PC. My comp at the time had a 4x CD Rom, his was x16. In eather case, the movie choped when you watched it off of the CD, but was cool when you copied it to the HD.
Till this day I have to copy that file to my HD even though I have 24x CD ROM.
