I am buying the DVD player in the link below and am just trying to figure out what DVDs to buy for it - it writes both DVD- and DVD+ (dual layer) but I have no idea what the difference is between those two and which one to go for. I reckon a DVD with standard storage (don't reckon I need dual layer) would do.
On my Sony DVD recorder, certain more advanced functions (such as 'chase playback' - start watching the start of the show you are currently recording) on work with -RW discs.
I guess that Rainyday is just pointing out some of the quirks of certain recordable DVD media and standalone players in case this is relevant to the original poster.
