Problem started in mid-May 2023 (after switching to BlueCurve wireless TV equipment in May 2022).  Live TV on Calgary CTV or Global started skipping during broadcast.  Sometimes switching to HGTV or other network seemed to clear skipping problem.  But sometimes required reset of TV boxes (BlueCurve wireless TV boxes) to get skipping or "black screen" on CTV or Global live feed to fix.  Shaw has changed modem once and TV boxes twice in the past 2 months.  However, STILL HAVING the same skipping issue.  So nothing resolved yet.  Calling SHAW only to have technician show up and the problem is not apparent when he/she arrives doesn't resolve anything.  Field technicians don't seem to know what is causing the problem.  Only seems to be occurring on live CTV and Global feeds -- I would suspect it is a background software issue that happened during a mid-May update and no one knows how to trace it back or fix it.  

Would be interested to hear if anyone else is having similar problems when watching live CTV or Global feed on BlueCurve TV (wireless TV boxes).
