Questions:

1. Are the two channels which (appear to) cause this on the same type of

tuner? Is it possible that the tuners use the same firmware/drivers and 
that two calls
at once is confusing the system.?

2.  Is is possible that these tuners take a long time to 'settle' when 
tuned?

Try changing the Tuning Timeout or Delay Lock setting.

3.  Finally, it could just be that the race condition is caused by the 
fact that there

are two simultaneous startups. Try changing the Recording Scheduling 
setup for *one* of those

programs, to start *one minute early*, so that the two are not 
simultaneous. I suspect that this is the easiest fix.G.
