Can anyone help ? I have a Marantz DV4200 dvd standalone player that I use in my AV set up. I'd like to know if anyone can give advice on which blank DVD-R media,would be most compatible with this player for watching backup dvd movies ? I have to used Datawrite Titanium's,Ritek Xtreme's,Verbatim DataLife+ & Mr Data,all DVD-R's,with varying amounts of success.The main problem is that sometimes these backup movies skip at irregular intervals,when played back in the Marantz,although are fine if watched using PC ! My recorder is a NEC nd3500AG & I use the latest firmware. Any advice appreciated !!!!!
