....incorrect, Blu-Ray medium is limited only by the ability of the current
hardware (read below).


Actually, HD-DVD format seems to be pretty much locked into the 36Mbps
data rate regardless of what's going on (read writing or reading) whereas
Blu-Ray will support 72Mbps (2x) at the minimum, and is looking to support
288Mbps (8x) or more. Really they are talking about stand-alone
player/recorder requirements when discussing supporting codecs. Bottom line
is this...

1) if your Blu-Ray player supports viewing jpegs, gifs, etc. then you can
do it.
2) if your Blu-Ray player supports .wmv files, then you can do it
3) etc, etc.

.... it'a all up to the player/recorders, not the Blu-Ray disc.
