There was an earlier thread asking about format conversion on S-video and composite video output ports.
In addition to direct HDMI connection to my 16:9 HD TV, I have connected a UHF regular NTSC modulator to provide a non-HD feed to my master antenna distribution system.
With the TV type set for 1080i yielding 16:9 for the HDMI (in setup TV type), the composite video output is a 4:3 width compression of the 16:9 video presentation.
This means a format setting of Pillar for showing non-HD 4:3 correctly on the 16:9 HD TV will show on the composite as a crunch width 4:3 with the black side bars. To get a normal non-HD to show correctly you have to change to 'stretched' mode so the stretched 16:9 will be compressed back to a 4:3 on the composite output.
With the TV type set to 16:9 for the HDMI, there is no mode setting to show an HD program without distortion. Again, it basically compresses the 16:9 down to 4:3 so the HD will have skinny people.
As the primary use is to feed the 16:9 HD TV I have not experimented with the setup options of lower res TV types as I don't want to compromise the HD TV feed. There may be a way to get the HD 16:9 program to present with black bars on top and bottom, preserving proper aspect ratio with 480i setup configuation.
