Am I right in thinking that the widescreen flag is recorded on DVD-R, DVD-RWs, but not for DVD+R & DVD+RW? Does this include DVD+RW Dual Layer? In the manual it states "DVD Rec. Picture Size works when recording mode is set to HQ, HSP, or SP. For all other recording modes, the screen is fixed at 4:3", does this mean it doesn't record in 16:9 in LSP?
