This is a message for the PVR people who write the programs that run the PVR. I have a Arris DCX3510-M PVR.
I sometimes don't watch a complete program at one time.
I may watch 20 minutes one day and then 40 minutes the next day.
If I reboot the PVR after watching 20 minutes the PVR will reset the start point to the very beginning of the program rather than the 20 minute mark.
Sometimes I may watch up to the 20 minute mark on one day and then the 50 minute mark the second day and then the 80 minute mark the third day.
If I reboot after the second day (50 minute mark) the PVR will reset the start point to the 20 minute mark rather than the 50 minute mark.
This has been happening for a long time.
