My Book AV questions

I think I know the answer, but will ask any way -

I want to be able to connect MyBook AV to my DVR (I already know its supported). 

The record/store my shows, then disconnect and connect to my Windows 7 Home Prem PC.

Problem is, each time the PC and the DVR ask to format the dirve - so every thing is lost.

Any work around?

Hello,

The DVR file system and the computer file system are different, therefore you won’t be able to do that.

Any suggestions then (to get the content off the DVR and onto my iPad) ?
