Hello. sounds like your disks are not compatible with your stand alone player. what brand are you using? Hope you're not using Memorex!!!! they sux! here is a media guide that will show you what's good and what's not: in mind that the better disks are made in Japan (MIJ). Taiyo Yuden, Verbatim, Sony, Maxell..... some good brand media! costs about the same as poor media! be aware of this and you can avoid many problems. If you still have a problem with your DVD player then you can booktype your disk to play like DVD-ROMs (which are more acceptible to most DVD players). Check out this thread, #12: that you should have no problems!
