PVR does not keep resolution when using HDMI switch

[Bear28]

Hi,

I have a Shaw 3416PVR and have noticed the following.

I have used 2 diff types of HDMI switches, one was a generic 4 port hub, and my latest is thru my new receiver.

The problem I have is that with the PVR you can set the resolution to be either 1080i/720p and 480i/480p respectively. I set both to P. I found that when using the HDMI generic switch, the PVR would go back to the default resolution of 480i/1080i about 50% of the time.

With my new receiver, it doesnt keep the setting at all and I have to change it every time.

Hopefully this makes sense

Does anyone know why this is happening?

Thanks
