I have a Philips DVDR70 recorder on its way, and was wondering about which blank media would be the best to buy. I believe it uses the DVD-R format, but I have seen some that say 4.7GB DATA on them (eg Maxell) - can these be used for recording TV/Film on to? Also, some media seem to have different speeds listed. Does it matter? Can anyone advise on best media to use and where to get it? Don't know whether its OK to go for a large spindle of discs or buy big brand ones. Thanks.
