I was surprised to notice, while checking out the (otherwise excellent) "sticky" thread at the top of the forum about Arcam software versions, that there's no mention of the transport firmware used in Arcam DVD players. This is distinct from the "software" - version numbers are of the form LT75, LT76, etc. If I understand correctly, it's firmware that's flashed directly into the DVD-ROM drive rather than controlling the player as a whole. I would have added this comment into the "sticky" thread itself, but apparently I'm not allowedto so I'll post it here instead. Could we have a breakdown of the latest "mech" firmware versions, and a list of what (if anything) changed between versions? I would also be quite interested to know what the different models of transport used in Arcam DVD players are (I know there are 3 or 4) and what the practical differences between them are.
