I have one two hour program that will not let me delete from my DVR. I do not have it in a lock mode..it simply will not delete. I have tried fast forwarding all the way to the end where the delete option automatically comes up...but it still will NOT delete! This is frustratng since it ended up being a show I did not want to watch and it is taking up 2hours of space on my DVR!! What can I do? This was just a regular network station recording also not a pay per view or movie channel recording.
