no...there's only ONE layer on a single layer dvd. if you fill the first layer the disc is full. you can't trick it into anything becaus ethere's simply no more room to put the data.
if you wish to burn dual layer dvds you muct purchase dual layer blanks
verbatim branded dual layer blank discs are really the only ones recommended at the moment. many burners and firmwares have trouble with other brands.
if you're going to burn DL media make sure your firmware is up to dat eas well.
