How to copy a DVD wath will play in a LG 5935?

I have a Lite on 411s and have try to burn with different media on DVD-R, DVD+R and DVD+R with bitsetting to DVD-ROM.
I can play the movies on different standalone DVD-players but not 1 DVD i have burnt will play int the LG’s standalone players.

They say that the LG is a -R player and if i have burnt a -R DVD de LG will not recognised the DVD. I get every time a Disc-Error in the display off the LG.

VCD and SVCD witch i have burnt with the 411s the LG plays.

BUT NOT 1 DVD I HAVE CREATED WITH THE LITE-ON 411s.

I have a AMD ATHLON 2000, with XP running and i use different media and software. I have burnt with a BTC drive before, and the same media plays in the LG;

Wath is my problem???

Try higher quality media and/or burning at a lower speed and/or a different firmware version (FS0F is generally best for DVD player compatibility on -R discs).
