Hi Sony RDR-HXD870B Editing on Hard Disk? 1. I understand from reading on this forum that this recorder can play back DVD-RAM discs. Given that it can, is it possible to do the following: a. Copy DVD-RAM discs to the Hard Drive? b. Edit the content on the Hard Drive and then burn new discs for playing in other recorders. 2. Is there a "best" DVD foramt for copying to, so that the discs will play on the majority of recorders? (Currently I have a Panasonic DMR HS2 that has been used to record everything off my Sony camcorder on to the Hard Drive and then moved across to DVD-RAM disk for storage. The Panasonic was only able to record to DVD-R (as well as DVD-RAM of course)). Many thanks in anticipation.
