ME TV

What happened to ME TV?  It used to be on Channel 41 and all of a sudden channel 41 disappeared!  I can now get Me TV on channel 371.  What's really strange is that on the TV with my main cable box I get everything that was on Channel 41.  On my smaller cable box I get ME TV programming until 9:00 pm and then it switches to GRIT.  So on channel 371 I get ME TV all the time and on my small box I get part ME TV and part GRIT.  Really weird!  How can I get all ME TV all the time?
