Resolution help for BD Rip?


Got what might turn out to be a daft question?

My HDR is set to 1080p using a HDMI cable. This is fine for freeview.

But when i play a BD Rip I've put on the HDD it outputs really bad. It stretches full screen horizontally and looks very pixelated? The film was ripped at 720p.

So I've had a look at the video settings and had a play? Why do I have to put the video settings to 4:3 and then letterbox to get it to dislay properly?

Have I done something wrong or missing something??

I hate 16:9 auto, this is a horrible view for a ripped film??

Can anybody point me in the right direction?

Cheers, Jon.
