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
> Initial recording window is set to:
> X:-5872   Y:0    Width:7792    Height:1080
> Adjusted recording window is set to:
> X:-5872   Y:4    Width:7792    Height:1072

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

Title:
  JACK audio source: "Improper window specification" (exit status 2816)

Status in gtk-recordmydesktop:
  New
Status in “gtk-recordmydesktop” package in Ubuntu:
  Confirmed

Bug description:
  It seems that running rMD (v0.3.8) on Oneiric, using JACK as audio
  input is broken:

  *) If JACK is selected as audio input, clicking the "record" button immediately returns with the message:
  "exited with status: 2816. Description: Improper window specification."

  *) I've found a HowTo-website describing the exact same behavior:
  (http://angel-de-vicente.blogspot.co.at/2011_01_01_archive.html)

  "[...] you can click "Use jack for audio capture", but with this
  option enabled I always got errors like "... exited with status: 2816.
  Description: Improper window specification.", so I decided to record
  the sound (with Ardour) and the video (with recordMyDesktop)
  separately, and then mix it with Kdenlive."

  Unfortunately, I want to use rMD to record Ardour itself - so I can't
  easily use his workaround.

  *) With rMD set to record the regular "DEFAULT" device (without JACK),
  the video transcoding (after stopping the recording), shows the
  progress-bar - staying at 0% infinitely. Until I quit "qjackctl". Then
  the rMD transcoding window closes itself, and outputs a broken .ogv
  file.

  *) When restarting the rMD GTK-GUI with "JACK" enabled as audio source, clicking "record", returns the following error message:
  "exited with status: 4352. Description: Port registration/connection failure."

  *) rMD also does not show up as JACK client at all.
