HDMI sends a pixel-by-pixel digital representation of the source video. Unfortunately there is no option to stretch or manipulate that using a HDMI connection.
You might try connecting your set with component cables, as I believe those options may be available with component cables.
I previously recorded (on DVD-RW+ 8x) a Star Trek TOS episode on my Sony RDR-HX715. When I play it back on BluRay, the ZOOM1/2 selection options are grayed out and not available. So I'm stuck with either a very tiny 4:3 picture in the middle of the screen, a somewhat stretched and slightly larger 16:9, or a very stretched out WIDE ZOOM image -- none of which fill the screen proportionately. Is there a setting somewhere else I'm missing, which will enable the ZOOM1/2 options?
My set up:
A/V Receiver - Pioneer Elite VSX-72TXV (HDMI-out --> TV-HDMI1-in)
Home Media HD DVR - FiosTV w/HD package (HDMI-out --> Rcvr-HDMI1-in)
Bluray player - Samsung BDP-3600 (HDMI-out --> Rcvr-HDMI-2-in)
TV - Samsung UN55-B8000
