I leave my Pioneer 414 DVD player (transport duties) on pause all the time. Sometimes for days at a time. Even weeks when I am on vacation. I rarely use "Stop". And, I have never had a problem with it. Granted, a relatively cheap machine will not cause the concern of a thousand dollar machine, nevertheless I don't think you need to worry assuming you have a quality machine to begin with - and I believe the Theta's are very good quality.
