Gemini won’t change screen format on SD channels

Just got a Gemini and every SD channel gets stretched wide. The screen format setting does nothing on SD channels — only on HD channels. The only recourse is to use the TV’s aspect override to Stretch Vertically every time we watch an SD channel.

This was not the case with the Genie. Its Screen Format option of Original did, in fact, keep the original aspect ratio on SD channels.

It seems that the Gemini force-stretches SD channels, overriding the Screen Format setting. Definitely a bug in the firmware!
