well TDK doesn’t say anything about the media. media ID is what’s important (this can be found in teh disc info tab of nero cd-dvd speed.
the most recommended media on this board is Taiyo Yuden (media ID YUDEN000T0X for +R and TYG0X for -R) and Verbatim (media ID MCC 00X for +R, MC02RG20 or something like that for -R)
basically any verbatims are a safe bet. TYs from www.rima.com are a good choice.
without knowing the media ID of your TDKs you really can’t make a judgement on whether or not its good media.
also, you might want to try slowing down your burn speed a bit. sometimes it’s a good idea to burn slightly slower than the rated speed especially on poor or questionable media. try your 16x discs booktyped to DVD-ROM at 12x or 8x and see if it will work then. Never select “max” as the burn speed. even if you’re burning at the maximum speed, select that speed! (ie 16x)
