Re: double images, bttv-0.7.107, PixelView PlayTV Pro

Excellent call Andy, thank you!

Although, I guess I should have been tipped off by the VIDIOCGCAP reporting max height and width of 970 something by 576.

The way that I fixed it, with you hint, was to request an image from the tuner, which when the code makes a call it sets the tuner to NTSC. Somehow that sets it also for the other inputs and subsequent VIDIOCGCAP reports max height and width 768 x 480 which is correct for USA NTSC for this device.

Now I should figure out how to set the norm on calls to the composite and SVideo inputs, using video for linux (not version 2).

Thanks again.
