No, the PVR-500 is still recording 4:3. This problem only occurred when I
switched hardware such that I no longer had a native TV-out and had to use
the HDMI->Composite converter. I'm not sure if the default HDMI EDID modes
even have a 4:3 option (but it doesn't really matter because the 720p looks
best with this converter). Anyway, it's strictly a display issue because it
happens with old recordings as well. I don't record any 16:9 content, but
some DVD rips do display incorrectly (16:9 fills the screen when it should
be letterboxed instead). We use videos infrequently, though, and it doesn't
really bother us. The problem will go away when we buy a new TV, but we're
not in any hurry...
