Regarding the Jeff Beck disc - thank you for all the responses..
Bob, I appreciate the info - I tried setting the de-interlacing from the TV and also the Oppo - my set-up on the Oppo since I've been using it is Auto for de-interlacing and set at 1080P - I haven't tried Source Direct because I assumed the Oppo would do a better job of de-interlacing the the Sony - also, yes , I fooled around with the "motion" processing (I usually have it set to the minimum or off ) and it made a subtle difference, not really better OR worse...
Looking at my post from last night, I realize I didn't mention the worst thing I'm seeing on this disc, which in fact might be caused by bad de-interlacing... what I called "motion blur" IS there ( mopar426 has it right, I think, with the cause of this), but the stranger thing is the "stuttering" I see- it reminds me of what it looks like while watching some PAL dvds being converted to NTSC - looks like a frame or frames being dropped every ,say, 10 seconds or so - this is the first disc I've seen this on using the Oppo.... this IS the first 1080i disc I've watched, although I've looked at plenty of DVDs on the set ( and come to think of it, I sometimes would see a "stutter " on these also, but VERY infrequently..) I find it hard to believe the Oppo would be having a problem with this , but I think I'm set up for the Oppo to be doing the de-interlacing ( Auto and 1080P ), but the TV must be doing something else, also (?)
I'll be borrowing a friends DVD version to compare, and I will take my disc and check out another player and TV to see how it works..
Thanks again for the info, any other thoughts, I'm open to them,
