[mythtv-users] PATCH for M179 on ivtv-0.6.1

[Dennis Lou]

The Aver M179 has a broken volume control.
In earlier versions of ivtv, you could set
the volume but it wouldn't do anything.  It
would always remain at 65535.  In ivtv 0.6.1
volume control for the M179 has been disabled.
However, Myth will abort opening mpeg recorder if
it can't set the volume.  This proposed patch
allows it to continue in this case.
