I have noticed a couple of times that I was waiting to watch a show that was recorded. I had manually deleted all the others. and it had been a couple of weeks and now it's gone. Is there some kind of automatic purge of programs if they remain unviewed? I missed the last episode of Lethal Weapon
It will automatically delete shows from the PTAT folder after 8 days(unless you lowered the save dates amount). If you saved the series to the "my recordings" partition of the DVr, they will be available until you delete them.
