Which brands of High Def STB do you know of that have functions that allow you to both set a time for automatic channel changes and will also allow you to manually set times for automatic channel changes. I could do this on my Standard Def Healing STB which was very good for recording consecutive programmes on different channels and to be able to set times that could alleviate the ongoing problem of stations deliberately running programs overtime. But I have just brought home an Olin HD STB Model HVBT-3400 and am very disappointed to find out that instead of having the same or better capabilities than the Healing,it is woefully inadequate in timer settings. These Olin HD STB's are currently being sold for $50 in Joyce Mayne. The salesman told me how they were their top selling STB. He said they had sold over 500 and had never had a complaint,.,.,.,well,I am definitely going to complain and go and get an exchange or a refund.
