>> In doing a quick test of the 2 pass mpeg this morning after changing the
location of the logfile, it worked.  But it did put out a couple of error
messages on pass 2which I am not too sure about.  However, when I ran pass
2 without having run pass 1 first, it put out correct standard error
messages and did not crash - which is good.  Attached you will see the 2
error messages on pass 2 as also shown below.  And my audio was not set up
to work but I am not sure if 2 passes even allow for that.
