First, to be clear, it is not HDPC, it is HDCP.
Is "Panasonic 50PG11" correct?
Do you have a second digital display in use?

"It’s not possible to use two digital outputs such as HDMI and DVI-D at the same time, but you may use the D-Sub output plus any of the digital options to run two displays."
Also, in order to use the HDMI connection to a (Windows 7 PC) system [where HDCP compliance is required to view HD Content], all of your HTPC system devices AND your HDTV must be fully HDCP compliant.
I suspect that while your large display can connect with HDMI, it is not HDCP compliant,
and while it will display the content,
it will not do so at HD quality. To test my theory, see if you can borrow/obtain a BluRay DVD player that connects with HDMI and you should note that your HDTV will play this beautifully (but not from a (Windows 7 PC) system where HD video can be captured and copied unless, again, all required system devices are known to be HDCP compatible).

These same restictions do, of course, affect recording or capturing of HD video. I have made several posts on these topics, just click my forum name to find them.
I suspect your other files were 'stretched' while encoding but are actually not 1080p files, yes?
I hope this helps.
