OK, it seems like there is a need to refresh everybody's memory about minus and plus. Technical differences: VERY little between DVD-R and DVD+R. However several independent tests show that approximately 83 out of 100 standalone player can read a DVD movie recorded on DVD+R instead of DVD-R's 71 out of a hundred. Well here you satisfy another 10 users (consumers) out of 100. For DVD-RW and DVD+RW however, the DVD+RW was especially designed for home video recording, it features lossless linking, which makes such recordings easier, more efficient and more compatible. Speed differences: DVD-R and DVD-RW seems to be one step ahead of speed increases over the plus formats, probably since it's a few years OLDER (did you all get that one - OLDER) technology. Hopefully plus will catch up one of these days. Price and Availability: Minus blanks are more widely available and cheaper at the moment. Plus NEEDS to do something about this if they want a better foothold. Supporters: Minus Formats - Pioneer and Apple Plus Formats - HP, Phillips, Ricoh, Sony, Thompson, Yamaha and sigh Microsoft, and because of the latter monopolist this format will probably prevail. For myself, I'll support the Plus formats since it's a more mature and consumer friendly format.
