did you take a look at the manual you should have recvd for your comcast remote control, You need to program your DVR, look in the manual for the 4 digit code and follow the instructions- usually- hold the dvr button on the remote down until it stops blinking- enter the code- (depending on who the manufact is) wait for the button to start then stop blinking, see if that helps

P0521 error indicates a problem with the oil pressure and/or sensing system Possible causes: Low oil level or motor mechanical fault
Open or short oil level sensor circuit condition
Poor oil level sensor electrical connection
Faulty oil pressure sensor The most likely cause is a faulty oil pressure sensor/switch Locate the sensor/switch and insure the wiring to the switch is in good condition ( CLEAN nad a solid connection) Replace the sensor

I just bought the CH-DVR 1600 @ Target. This is just a temporary workaround to enable playing of region 2 DVD disks (don't have other regions but believe it will work also), until the real regional unlock is available.

1. Insert the region 2 DVD disk and close the tray.
2. Wait for the "Wrong Region" popup to appear in the upper-right corner of your TV screen.
3. The display on your DRV reads "STOP" at this point and the "Wrong Region" popup has disappeared.
4. Press the number "1" button on your DVR remote and a small input popup will appear in the upper-left corner of your screen.
5. Do not press anything else and the DVR will accept this entry as a chapter # and proceed to this chapter to start playing the movie.

NOTE1: The DVR runs in a somewhat restricted node, e.g. the DVR display still reads "STOP" and some remote functions do not work, such as "Menu". The input numbers correspond to the chapters on the DVD disk, so you can experiment and get to the menu once you hit one of the extra feature chapters with a "back to the menu" link on it.

NOTE2: I’m anxiously awaiting the real unlock sequence, as I tried most of the old ones posted here, none seemed to work.

also try this
-Switch player ON with no disc in the tray. Close tray and press MENU, 1, and 9 on the remote control. A menu should appear with the Region Option. Highlight the Region entry and press ENTER on the remote. Type in the Region you want. (Put 0 for code free) Press ENTER again to confirm choice. Press OPEN/CLOSE TRAY button and put in movie.

you may need to clean the lens of drive with a wet tissu paper, otherwise the drive might gone out of order, need replacement.

it's windows issue, you just need to edit windows registry.
