One of our 2 HR21 DVRs has been locking up lately, and have a replacement unit here. The issue is: the old DVR series manager is full with 50 items. Some of the items are seasonal, and others mainly of the local PBS stations are no schedule, just seem to appear randomly, some less than 1/month. Even to enter by hand each item, many would not be possibly since they wouldn't appear in the guide until 2 weeks prior to airing. We are current with watching recorded programming, so, there is nothing there to transfer. Assuming that the DVR has Linux OS, the data is likely a file in the user's area (some name), would it be possible to copy the file to a PC running Linux (I have several running Ubuntu), and then copy the file to the new HR21. Understand that means opening both of the boxes. I am somewhat familiar with Linux, Gparted, and Clonezilla. Some questions, hopefully someone has access to the contents of a hard drive: 1: Is the Series manager data a single file, and it's name? 2: Is the file(s) encrypted? If not could one search the file for a text string to find the file? 3: Would the HR21 see the different file size, and flag that as an error? 4: Would back up the new drive with Clonezilla, and if necessary restore it. 5: Has anyone done this? 6: The old HR21 is operational, if it is returned with a missing tamper seal, is that a concern? 7: Using 2PC, is there a way to enter the series manager data easier than using the remote control? Thanking in advance for any comments.
