On one of my Vip 622 receivers with L449 software I watched last show that I had on the DVR list and deleted after watching it and there is a DVR event recording with no name and 0:00 as the time limit. When I arrow over to the event it says Event Expired and when I press select to go in to the event and delete it I get a pop up saying "This event is currently in use and cannot be deleted at this time. Please try again later." There are no more recordings on my dvr list and the HD time limit is 30hr 0 min and the SD: time limit is 199hr 59min available. What is in the receiver that takes up 1 minute? Now when I exit out of the DVR menu and watch live TV then go back to the DVR menu the event with no name dose not show up and the SD time limit is still 199hr59min and the HD time limit is 30hr 0 min. Is this a glitch in the software on the VIP 622 receiver or is it just my receiver?
