The interlace settings in mythtv have nothing to do with the pvr350 output
if you use the hardware decompressor (be sure you checked the pvr350
output in the options, otherwise you may do software decompression on the
framebuffer, which is slower and less sharp)
Howerver, the hardware flickerfilter does reduce sharpness. Be sure it is
desactivated with ivtvfbctl.
