A very tiny bit, perhaps. You can set chroma, luma, brightness and 
contrast w/either nvtv's gui or with command-line switches. However, 
you can do all that in the MythTV frontend already, so its kinda 
redundant. The biggest place nvtv is useful is if you have a 
pre-GF4-series card and want/need overscan.

You can modify settings on the fly with nvtv, while overscan 
adjustments in XF86Config will require a reload of X. I don't touch 
nvtv on my GF4MX-equipped system, since you should really only have to 
tweak the settings once and leave 'em. Only my secondary system (w/a 
GF2MX) uses nvtv.

Certainly not in my case. The GF4MX system is hooked to a 47" HDTV, the 
GF2MX system to a 27" analog tube. ;-)

Along with the other stuff I already mentioned, I believe it may 
support a wider variety of TV encoder chips than the nvidia driver.

Also, note that you can use both the nvidia driver and nvtv at the same 
time. That's what I'm doing on my GF2MX.
