Aspect ratio problem
I have Spectrum Choice streaming TV service, using a Roku 2 Internet device. It works well; however, I find myself having to change the aspect ratio of the picture manually every time I change channels from an HD channel to an SD one (if I don't do this, the picture appears on my TV with two black bars at either side). I find this very annoying, as I watch programs on DTV subchannels of standard TV broadcast channels in the Cleveland area. These DTV subchannels all carry older TV shows from the 1950s through the '70s, which were filmed or taped in 4:3 aspect ratio. This means I must change the aspect ratio setting of my TV every time I go from a channel having SD programs to one with HD programming, or vice-versa. Is there a way I can set my TV, or the Roku device, to automatically detect the aspect ratio of a given program and adjust the picture size accordingly, or is there a software update to address this issue? The Roku 2 does not seem to have any kind of provision for this, although the Roku 1 (I still have one) did have a setting for 4:3 aspect ratio in its main menu.
