Proposed patch - External recorder channel change can result in discontinuous changes for LiveTV

[Gary Buhrmaster]

For your consideration:

During some testing of LiveTV with an external recorder (limited testing, I almost never use LiveTV) I encountered some non-reproducible issues with channel changes and video failures. I originally thought I had tracked them down to changes in video format between the channels, and applied the following patch, which seemed to help at least a few times.

Eventually I also made other changes to my external recorder to eliminate certain other channel change artifacts.

I have been unable to reproduce the original problem with or without this patch since I made those other changes to my external recorder. But this feels like it should be the correct value for the general case of external recorders and LiveTV.
