I recently switched from an ancient Hauppauge PVR box to a simple HDMI <br>
capture card and am setting it up as an external recorder using the wiki <br>
and some config suggestions from list member Dave Pearson (thanks Dave!).<br>
<br>
Scheduled recordings work, but for reasons that aren't clear to me the <br>
output is just digital noise. I could use help in understanding why –– <br>
configs and logs pasted below.<br>
<br>
My setup is the HDMI input of the capture device [1] connected to the <br>
the HDMI port of my set Arris DCX3200-M top box (via a 2-port powered <br>
HDMI splitter [2] for viewing live TV). In mythtv-setup I use the 6200ch <br>
command to change channels (and this works when executed manually).<br>
<br>
Config files and logs from a sample bad recording below. Thanks in <br>
advance for helping understand what's missing here.<br>
