I was out of town for a few days and got back last night. I turned on the TV, and started to watch a previously recorded show.
The screen froze on the live TV program, and stop, pause, rewind, FF did not work. I could bring up the menu, but selecting anything on it would not unfreeze the picture.
I jumped on the forum to see if anyone else was experiencing this problem. After about 10 minutes the recorded program started to play. It played for about 15 minutes and then froze again.
This DVR was a replacement for my original that crashed several times, losing all of my recorded programs. I was reluctant to reboot it, because that was how I lost all my shows the last time. It reformatted my drive.
While the show was playing I pressed stop, FF, Rew and nothing happened, and the progress bar was totally messed up. It had a huge number for the current time and the progress bar extended off the right side of the screen.
See the image below.
After the 2nd freeze I rebooted, and I'm happy to say the DVR is back to normal. I was able to see that it had not yet downloaded the latest update, so there might have been an issue with that. I tried to manually force the update but it didn't do it. It seemed to download the update, but then it didn't install it. I'll have to try again now that it was rebooted.
