[mythtv-users] questions re Component Out with Nvidia 6150

[Craig Courtney]

Keep in mind that these chips have two sets of output circuits VGA  
and TV Encoder.  The VGA (either analog or digital through DVI) may  
very well not be capable of doing interlaced timings anymore, but the  
TV Encoder chip must deal with interlaced modes to deal with both  
ATSC and NTSC standards.  Either way the only component on your  
system that knows the difference is the output circuits on the Video  
card.  The operating system and applications see it as a full  
resolution frame buffer.  How the video card sends this data to the  
display device can be completely different just like DVI-D and VGA  
are completely different types of signaling to the monitor.
