Black screen using Blueray player or DVB-T receiver as HDMI input device

[BSI-Dual65]

We have a problem with our Cisco Telepresence Profile 65 Dual (C90, MultiSite, NaturalPresenter, Premium Resolution, Firmware TC5.1.4.295090):

Using a document camera connected via HDMI (as input source 'DVD'): works well.

Using a DVB-T receiver connected via the same HDMI input (as input source 'DVD'): black screen

Using a Sony Blueray player connected via the same HDMI input (as input source 'DVD'): shows the Sony startup animation when switching the Blueray player on, then: black screen

Seems to be a problem with the Codec. When connected directly to the HDMI input of the screen, the Blueray player works well.

Any suggestions for solving this problem?
