Thanks for the info.  I ran the above and everything looks great.
Video statistics --
81451 packets received, 0 overflow errors, 0 network errors, 0 transport
errors, 0 sequence errors

 I also tried a different drive and storage group for live. TV.  No joy.

If anything. It seems like live TV starts to fast.  Much faster than ,27
did imo.
If I exit. And start again it is fine
