PiCorePlayer as wireless bridge

Hi

I understand PiCorePlayer can work as a Wifi access point but I'd like to use it as a wireless bridge (like the old SB3 once did).

Specifically I'd like to connect the Pi to a PVR by ethernet cable so the PVR can update the EPG over the Pi's wifi.
If I can't do this, I can always get a USB wifi adapter to plug into the PVR, but I thought this might be a more interesting approach.


So, can I include user commands at the startup that would bridge the ethernet port to the wireless port?
But I presume I'd want to do this after the Wifi has been configured rather than before?

I did find that this https://sourceforge.net/projects/bridger/
But wouldn't know where to start....

Thanks
