Cyberhome 300S Question

Picked up a Cyberhome 300s, mfg. date Nov.2003 [Setup shows 300s.20.03]
The unit works without any problems using a commercial disk. A disk burned in my il0 RHD04, RO4 or Lighton 5045 the will not play. This is for a –R/RW or +R/RW
I do not use the ilo’s or Lighton for play.
I am using two Cyberhome 1600 for this and do not have any problems These things will play almost anything. The 300s was for an RV..
Commercial disk OK,.When a burned disk is used the unit will display a menu
On top is -- Disk, -choices right below are Video, Video_RM , Video_TS
Below that are Display and Playmode
Selections can be made but are not permanent and I can not get any further
I have looked through a downloaded Manual and have not seen an answer here or in the fourms Hopefully I am not doing what the unit wants and do not see it.
