thanks. i though ti "had " to use 24 flac with dvd-audio? you're saying use the 24 bit wav?
yes, you can use 24 bit WAV (or FLAC files)
as far as flac goes, when i hit the "about" button, it does say v1.7.1.
as I said in my first post, that is just the version of the Frontend (i.e. the windows GUI aka "Graphical User Interface", which is there so you don't have to use DOS commands). But the version of the frontend is different from the version of the actual FLAC encoding. The next time that you encode or decode FLAC files, pay attention to the DOS window that pops up, and that will tell you which version of FLAC you have installed.
I just tried again with a newer flaced show and didn't work, but when using an older flaced show it did?
this is most likely because the newer 24 bit FLAC'ed show was encoded with FLAC v1.2.1, which your version of DVD-Audiofile
can't handle, while the older 24 bit FLAC show you have was encoded with a older version of FLAC, which DVD-Audiofile
can handle.
Try decoding to WAV, and then creating the ISO.
