I configured the LCD TV screen as a second X display in nvidia-settings, as you suggested, and it works! The tearing goes away. Thanks a bunch!

It's most noticeable in high-motion scenes. It's almost as if half of one frame is being displayed along with half of the previous frame. This doesn't occur if I play the same exact content on my computer monitor which has the same resolution, but connects to the PC via a DVI cable. (NOTE: this effect isn't caused by interlacing. I know what that looks like and this is different.). The problem occurs if I play MPEG files, or even raw RGB files, so it isn't caused by the CPU being too slow to decode the MPEG video.

As explained by Phil.
If your trying to play on both the monitor and TV you will only get
vsync on one of them.
I don't know if you can choose which to sync to with nvidia drivers, but
it's worth looking.
Maybe the easiest thing to do would be to set up a second screen - I
don't know centos (or any distro) or what desktop you use, so can't say
what exactly you should do - maybe nvidia driver options will let you
set the TV as a separate screen.
