I have a number of Sony BDP-CX7000ES 400-disc Blu-ray Players in my setup. My PEP v1.1.20 configuration file
(as seen here) includes a full set of IR and RS-232 codes. I have a number of Sony DVP-CX985V 400-disc DVD Players in my setup as well which use the same IR codes as the Sony DVP-CX777ES. The IR codes for Sony's 400-disc DVD Players aren't the same as what's used for Sony's 400-disc Blu-ray Players. See my reply to your other post
here, Len. My reply in your other thread covers all the bases for you.
