Every time we record a show on our DVR (501) it records for 1 minute less than it should. For example a 1 hour show will come up in our DVR menu with a duration of 59 minutes. Likewise a 30 minute show will only record 29 minutes. We have had 3 DVRs for several years now and all of sudden in the last week or so all 3 of them cannot record a whole show. Something has obviously changed at the Dish Network end of things, but I can't even get tech support to understand the problem. Is anyone else experiencing this issue? The tech support solution is to use manual timers for everything. What a worthless and rediculous fix.
