Update of /usr/mash/src/repository/mash/mash-1/tcl/nsdr
In directory gumby.cs.berkeley.edu:/tmp/cvs-serv8544

Modified Files:
	ui-mediaedit.tcl 
Log Message:
Fixed so nsdr is compatible with sdr.  The media payload types need to be
numbers, not names.

Matt actually fixed this problem in revision 1.13, but the fix was incomplete.
This caused crashes when switching between streams during the creation of an
announcement.

Andrew fixed the crashes by deleting Matt's code in revision 1.18, thus making
nsdr incompatible with sdr again.

I reinstated Matt's code and added a little more code so nsdr won't crash when
you're editing a new announcement.
