My understanding from an engineer that designs stb's, is that with dvi,
the rgb is converted to digital inside the stb for "access control purposes"and then decoded again by the monitor. This is confirmed by
examining the schematic of my sony 40xbr800 and 50xbr800..which would
support what scoffer says about PQ being better with component..
I haven't actualy tried that, but now I will.
The digital audio is constant as it is not audio, but actually data in AC3 format, and it is practically impossible to change the level of the digital output in that form. Hence it has to be done after decoding to analog.
As to toslink cables,I agree with you on that point Hugh, I have an over priced monster crapple optical cable that has fallen apart on me.
MCM Electronics has a great selection of toslink cables that are just as good, cost significantly less, and are better made IMHO! They have them
in up to 30' lengths, and kits that you can make your own custom
lengths as well.

Nor my wife for that matter!
