You could use $gettok for the first and you could combine $gettok with $remove for the second...
$gettok(‹‹new›› ‹‹dvdr-nordic›› The.Kite.Runner.2007.NORDiC.PAL.DVDR-SUBTiTLES by Slaktarn,3--3,32)
$remove($gettok(‹‹new›› ‹‹dvdr-nordic›› The.Kite.Runner.2007.NORDiC.PAL.DVDR-SUBTiTLES by Slaktarn,2,32),‹,›)
//echo -ae $gettok(‹‹new›› ‹‹dvdr-nordic›› The.Kite.Runner.2007.NORDiC.PAL.DVDR-SUBTiTLES by Slaktarn,3--3,32) <-- first
-
The.Kite.Runner.2007.NORDiC.PAL.DVDR-SUBTiTLES <-- first
-
//echo -ae $remove($gettok(‹‹new›› ‹‹dvdr-nordic›› The.Kite.Runner.2007.NORDiC.PAL.DVDR-SUBTiTLES by Slaktarn,2,32),‹,›) <-- second
-
