Oh well :-(

Shame, as I thought, it being a panasonic blu ray player.. it might work.. :-(

I had the same problem with Hamry's SW blu ray ISO image.

This helped to play the file on my standalone, maybe you will get your image playable too if you try this:

Mount the ISO image in daemon tools or a similar tool.

Then open the BDMV folder. Are there other folders named AUXDATA, BDJO, JAR, META in the BDMV folder?

If not, I have no idea to get this one playable on your standalone. :-(

If these folders are there follow my little guide:

Copy/paste the BDMV folder and the CERTIFICATE folder from the image you mounted into another folder on your HDD, for example C//:videos. You could also skip this step but I really recommend to do this.

When finished, delete the following subfolders in the BDMV folder you copied:

\BDMV\AUXDATA\
\BDMV\BDJO
\BDMV\JAR
\BDMV\META
\BDMV\BACKUP\BDJO

Important: Do not delete the BACKUP folder, only the BDJO folder in the BACKUP folder.

Then burn the BDMV folder and the CERTIFICATE folder on your disc as described in this guide. Your disc should play now.

Some standalones cannot handle discs that contain the subfolders mentioned. My player cannot handle them too, but this helped.
