Re: [ivtv-devel] framebuffer or decoder, but not both

[Pete G. <pe...@go...>]

Hi Zach,
It sounds likely to be a configuration setting you need to set.  There is=
 a
place in mythfrontend where you need to tell it to output the video to yo=
ur
PVR-350 TVout.  Go to: Setup > TVSettings > Playback > (next >) and enabl=
e
the "Use the PVR-350's TV out/ MPEG decoder" checkbox. Also, make sure yo=
u
have the correct video device listed in the box below.

I hope that's all it is.

Pete
