I completed the upgrade from a 3618 to a 3688 and I must say that I am kinda disappointed. Though I have only played with it for about 24 hours, I will try to let time change my opinion. I found it not very user friendly, with my main complaint that you can't edit the PIDs and the FRs and SRs on the same screen, took me a better part of 3 hours to figure how to combine the two. And I am still not sure how to do it. Another thing I found out, by accident is the touchy delete button. On the 3618 after you hit delete, it asks you if you are sure you want to do it and gives you a chance to make up your mind. With this baby, you screw up and it's over, dropped 39 channels and about 2 hours work in one flip of the switch. Also there are no icons for ceratin satellites. How can I scan AMC 9 when there is not a position. Also no AMC 6, I put the G6 in that position and it worked fine. I am slaving this through the 922, so I figure any icon that matches the LNB band will work, right? I am also having trouble doing blind scans, I have figured out TP scans with no problem. Come on guys, someone help me out here. I am not one to judge things quickly so I will give it a chance, I know I will like it in the end.
