I did read the post...Read his first post. He wants to be able to archive his CD's to a few DVD's to be able to conveniently play them via his Blu-ray player. I assume that the player has no means of connecting a flash drive or USB hard drive or network with the music files on it. Also he is on a limited budget.
I'm simply interested to know what other storage methods he's tried. And now you've mentioned it, the make and model of Blu-ray player too.
Just so people know... Even though it may not be stated within the players user manual, many players support playback of .mp3 files burned as data files onto CD-R or even DVD~R media.
