As an inadvertant learning experience while trying to access a particular recording copied to USB HDD by the HDR, I discovered that it was formatted (by the HDR) with 256b inodes, which initially gave me some issues with mounting it. I reformatted it on my PC with 128b inodes and it's fine as far as both the HDR and other systems are now concerned. 'Backwards compatability'! Anyway, I noticed, as a consequence of the reformatting, something I originally noticed when I formatted it with the Humax. Although I wondered at the time what it was, I didn't investigate then and the Humax reverted to showing the TV channel. What I saw was an 'additional' Copy icon after the Video, Photo, Music icons on the Media page it displayed. This time I selected it and it had 4 options: Copy V,P & M 'Automatically', and one each for V,P & M. to copy 'Manually'. Of course while I was thinking about what this meant, it reverted again (having presumably chosen a default itself). Subsequently. this icon no longer appears if you select Media (yellow) button on the appropriate screen. Will someone enlighten me on what these options do, and why you only seem to get 'one shot' at doing anything about them? Thanks.
