Hi ilaleary - -
Might you kindly elaborate a bit more, please?
Which of the 'DVRs' available @ DISH? ... i.e. - their VIP-722 ?
Surround Sound Receiver involved?
Whenever they made a trial w/ R,B,G Component cabling, in what way or manner did the P.Q. worsen? - i.e.- less bright, fuzzy, etc.? That HAD to be through a different "in" port of that Sony .... was that one also "calibrated" before a decision had been made? { ALL ports or connection 'inputs" must be calibrated separately, one-after-the-next} AND, very FEW of those Factory Defaults will be kept at all.
Qood Quality "RCA" Component Cables should NOT make a visually-discerible difference in P.Q. .... your reference to ...HDMI for the best 'HD" ... ONLY applies to Blu Ray or Game Consoles, Upconverting DVD Players, etc., wherein Much More Data or bits are being "tossed about" / transferred per second - - - NOT the case with normal .. 720p .. & .. 1080i .. broadcasting, however!
Should have tried / used good RG-6 .... here ... item #2773 ...

Won't "solve" your issue - BUT - I'll lay heavy odds against that DISH Service - it ISN'T that Sony .... try a "temporary" antenna / watch some 'HD" from O.T.A. & prove that it IS ... DISH!
At the large "risk" of offending Many herein - THAT is the main "issue" I have found w/ satellite service over the years ... whenever they can not or will not "FIX" the problems , it is always ...YOUR TV set ... , as they drive off into the sunset .... often @ $29.99 per each house call !

p.s. - before someone "asks" - - - yes, I definitely AM a staunch / forever Sony (plus Panasonic Plasma since the loss of Pioneer!) advocate ... Ours happens to be their 52" + 40" .. W3000
