I think its all different for each brand but many of them support these "legacy" formats. I know the Samsung's support just about everything and the Panasonic supports side-by-side. Not sure about the other brands.
Thanks for that.
I guess I should have been a little clearer in what I'm after. I was thinking that people that own the TV could list what TV they have and what formats they can confirm work through which interface.
For example (please don't take this as reference because I have no idea):
Samsung - PN58C8000
- Side-by-side - through HDMI only
- Interlaced - through component input only
If this makes any sense?
