@Nighthawk6 -- there is no content when I try to play them
Did you record a program on a channel that you were not subscribed to, at the time that it recorded it? That would explain "no content".
> the PVR does not provide any way to delete them.
If you can see the listing of recorded programs, you should be able to select it, and then delete it.
> I believe they will be gone if I format my disk.
That is correct, because "formatting" completely erases the "table-of-contents", which lists all the recordings.
> How can I format my disk?
Good question. The answer depends on which PVR you have -- namely the DCX3510.
There is some "secret" key-sequence at "power-on" time that accesses the PVR's internal menu (not the Shaw menu). There might be an option on that menu to "format" the disk-drive.
The other method is more difficult: partially disassemble the PVR, and remove the disk-drive, and temporarily connect it to a "disk-drive-to-USB" adapter device, and connect it to your computer, as an "external disk-drive". Microsoft Windows can be used to "format" it. Note that its format is not compatible with the format that the PVR uses. So, when you reconnect the disk-drive back into the PVR, the PVR will insist on reformatting it, which is what you want.
While the disk-drive is out of the PVR, check the manufacture-date on the disk's label. You probably have a 4 to 8 year old disk-drive -- far beyond its 1 or 2 year warranty, and getting close to its expected lifetime. That's a completely different issue.
