[mythtv-users] Horizontal Distortion on OTA ATSC

[Jonno]

Here is my setup:

OTA ATSC -> hd5500 -> nVidia 6150 on-board with nVidia driver ->
Composite -> 4:3 CRT tv

I am seeing horizontal lines of distortion whenever there is fast
movement (static images look fine) on screen in the following aspect
ratios:
4:3, 16:9, 16:9 stretch
I DON'T see the distortion when using 4:3 zoom or 16:9 zoom.

Not sure what aspect ratio the broadcasts are in.

I do not have deinterlacing selected in the playback options.

For watching regular tv I'm fairly happy with 16:9 zoom since there
isn't much useful happening on the edges but I need to be able to
switch to 16:9 stretch when watching movies. Any ideas where I should
start trying settings?

Jonno.
