It is stupid that there were even two standards in the first place. Add in the rewritable formats and then the dual layer variants and its a mess. I think DVD+R is actually better from a technical standpoint than DVD-R but it isn't as compatible with older hardware.

My LG drive can read but not write HD DVD discs as well. I can find sites that sell internal LG writers but the LG site for the UK only lists external drives and everything else is discontinued. Not sure what is going on there.
