I have a 722k receiver and have problems with the timers that I setup. Every night I have to go through the guide to make sure my shows are recording and always coming across a few that are set to record but when I look at the timer I previously setup it will be blank and after setting a new timer for that show it may work for a week and do the same thing. This happens with several timers. I currently had about 68 timers and at-least 14 are blank even though there are new shows coming on but doesn't even show the ones that are repeats they are completely blank. I have only had Dish for about 3 months and after being on my third dvr I got them to send tech support to my house and they spent over an hr here and couldn't really just changed things and said try that and didn't work because tech just left again and this time replaced the dvr so now my 4th dvr in 3 months and they still have to as to why. Doesn't matter if set to record in SD or HD. Does anyone else have this issue?
