I set the time to change channels and start recording at a certain time. The recorder went on as scheduled but the channel never changed. The writing on top of the screen changed, and the files recorded reflected that change in screen but the content was from the previous channel. This is a feature that made me want to buy this product and it flat out doesn't work. I think some sort of reimbursement is in order for this product since what it's advertised to do doesn't work. I have to be there to physically change the channels and click and click and click and click to do get it to work as it is. I'm sorry i bought this product since I've had nothing but problems relating to channel changing at crucial times from the git go.
