Odd...I have had two units (post - red dot, then blue dot) and have not seen any video switching problems (up-conversioning is not the best but decent). Could this be symptomatic of being B-Stock? These units may have had other quality issues...before you spend oodles more for one of the clones, I would suggest a slight cost increase for an A-Stock 950 or just keep playing 950 roulette on the B-Stocks until you get one you are happy with.
