Morphos people are waiting for the new version of fryingpan to be released, which apparently gets over the 2Gb limit.
For burning ISO images under Make CD you need the DAO (Disk at Once) version, which can also be used to make images.
I have used Nero 5.5 to make Amiga CDs, they work ok, but as pointed out it misses some of the flags which can cause problems. Obviously Nero 5.5 is of no help whatsoever when trying to burn a CD from an Amiga.
As for the other stuff, verification is the only thing really missing from MakeCD for most people (and for myself I'm quite capable of doing a few quick checks anyway, which is enough for me).
If your DVD player needs a disk recorded in SVCD format it must be very out of date - mine is over a year old and will read any MPeg file from any CD.
Can't comment on copying Playstation CDs, as I've yet to see a Playstation game I wanted - obviously thats making illegal copies too, which is something I avoid anyway.
@Doomy - I hope you have expressed permission from the copywrite holders to be commercially reproducing their stuff, otherwise this is piracy. Just because it's on Back2Roots doesn't mean you can bung it on a CD and /sell/ it! (see their acceptable use policy).
