Comment(by Quozl):

 Tested on os119, with a change to Record that adds "device=plughw:0,0"
 after the two instances of "alsasrc" in file glive.py, on the
 recommendation of jnettlet.

 With this change, and the changes up to and including os119, the Record
 activity video mode is no longer choppy and does work.  There is a
 repeating image defect that is thought to be related to the VIA DMA
 engine, and this is being investigated.
 http://dev.laptop.org/~quozl/10045.ogv is an example.

 Without this change, a recording is played back at an incorrect speed.

 Refer to #10070 for related test method and results.
