Problems using DSP settings on Yamaha 863 amplifier

[Devlin1980]

Hi,

I've recently noticed that i am unable to select any DSP mode other than straight when watching Blu-rays on my Yamaha 863 amp. For everything else (sky, DVDs etc) i can select any mode i wish but for some reason these options are unavailable as soon as i watch a blu-ray.

Has anyone experienced anything like this before or have any suggestions how to fix it?

Currently using an Oppo BDP-83 for DVDs and Blu-rays.

Any help would be appreciated.

Cheers,

I have the '763. When there is a hd soundtrack inputting into the amp you cannot alter the sound, any other none-hd feed can be altered,
