Also when I use gorecord with the following:
gorecord -input 2 -tvchan ntsc-bcast:20 -duration 60 -format mpeg4
-bitrate 4000 capture20.mp4
VIDEO: [DX50] 640x480 24bpp 29.970 fps 3693.0 kbps (450.8 kbyte/s)
So I am pretty certain that I have a NTSC unit.
But when Myth does a recording MPlayer reports:
Detected MythTV stream, reading extended format information
VIDEO: [XVID] 640x480 25.00 fps
I can't find any location to set the FPS and I'm manually made sure
that my channels are set to NTSC.
