Comment 6 for bug 1037402

Here's a bread crumb. I edited /usr/lib/python2.7/dist-packages/recordMyDesktop/rmdTrayIcon.py to dump the full command-line:

$ recordmydesktop -o /home/nhilton/Desktop/rmd1.ogv --fps 30 -x 527 -y 320 --width 877 --height 571 --channels 1 --freq 48000 --v_quality 63 --s_quality 10 --workdir /tmp --overwrite --use-jack system:playback_1 system:capture_1

> Window size specification out of bounds!(current resolution:1920x1080)

The windows parameters x, y, width, height all looked okay to me. So next I tried to running without any windows parameters:

$ recordmydesktop -o /home/nhilton/Desktop/rmd1.ogv --fps 30 --channels 1 --freq 48000 --v_quality 63 --s_quality 10 --workdir /tmp --overwrite --use-jack system:playback_1 system:capture_1

The window dimensions look odd, but then we get the underlying JACK error.
