Sorry to be a moron - this has probably already been answered a thousand times before but I can't find the answer. I'm pretty sure that the DMRE50 is better than the DVDR70, but there is one problem (I think!) that is stopping me. Am I right in thinking that the DMRE50 records on DVD-R only? And therefore u need to buy DVD-Rs?? Whereas the Philips uses DVD-RW format, meaning that you don't have to purchase lots and lots of blank DVDs to record on, as you can simply record over your previous recordings when you have finished with them, which is akin to video recording? Is this a big issue/concern? I've seen the review and I know the DMRE50 gets 5 stars to the DVDR70's 4 stars, but surely DVD-R is a pain, meaning that you have to purchase lots of blank DVDs very regularly, if you do lots of recording? Thanks for your help.
