Using the same software, I rendered the slide show to a high definition MPEG2 file. I burned the MPEG2 file to a blu-ray disk (since it was too large to burn to a standard dvd). Using my laptop with a blu-ray drive, I can run the MPEG2 file and it runs perfectly. I know that some Blu-ray players can play MPEG2 files - the one that will be used is a Sony, am still waiting on the model number. When I burned the file to disk this morning, I used the 'write files to disk'. There were several Image Options available - I randomly chose Mode1/2048, UDF 1.02. The end result worked in my laptop but maybe different options would improve the chances that a commerical blu-ray player could read the file. Would you know how best to set those Image Options? Again, am just writing a MPEG2 file to disk not messing with the ISO file which is unplayable.
