Ever seen this kind of error? Where do I start?

Question

Trying to burn a DVd in DVD studio. It formats successfully and happily ejects my DVD but the Log info has the following in orange lettering:
Warning: The file ‘JMDVD.img’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘GPADVD_PROJECTII.layout’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
When I try to play in standard DVD player it reads forever and never mounts.

Answer 1

The JMDVD image file is something you have made earlier and is sitting in the build location folder. Remove it - that file, the .lay and .layout files have no business inside the VIDEO_TS folder that DVDSP is going to make for you. The orange warnings are in fact just warnings, not errors... they are simply telling you what is going on.
Why your disc won't mount could be entirely unrelated to any of this. It could simply be that you have used a very high bitrate, or you've got a brand of disc that doesn't work too well in that player, or any other minor error. Have you tried the disc in a different player? A computer? Have you tried to re-burn, with a lower bitrate for the encoding? How are you encoding? What audio format are you using? The list of possible issues is endless... but suffice to say the warnings are not going to be the reason your disc doesn't play in that player.
