The more I think about this AC-3 isn't that important right now. I do have around 400 LD's and maybe a dozen are AC-3. I think I have more DTS. I sucked them up when ever I found them. BTW, most of the discs were purchased used, dirt cheap, after everyone had to have DVD's.
The problem could be the DVL-909. Checked my connections and still black & white. I have a CLD-79 I'll hook up and I picked up a Sony STR-DG820 for under a $100 because it has HDMI inputs. It's a little short on power but I have a pair of powered Velodyne F-1200's in my set up so that's not a concern. I have a Sherwood R-945 hooked up now and it has AC-3 but no HDMI inputs. I'll pick up a composite to HDMI converter for the LD and a HDMI switcher as my TV only has 2 inputs for my HD cable signal and Blu-Ray.
The Sherwood does have a AC-3 input. I also have a Yamaha DSP-A1, but I need to get it looked at, left channel problem. That's the one I really want to have in my setup.
Why did you go with the BK demodulator? My 1st choice was going to be the Pioneer RFD-1 then if not that, the Yamaha ADP-1 or 2. Found a used ADP-1 for $120, delivered. Also a Sony Mod RF-1 for $150. That's it! These things appear to be pretty scarce. I know nothing about them because I never needed one but it looks like I'll have no choice with a newer receiver. I'm debating buying one because they are probably not making them anymore. Is there much difference between brands? I can't find out much before I buy one.
Thanks for replying.
