Anyway, I can tell you that it's not restricted to enhanced files as such, it's just that the file dialogue is defaulting to show only .aax files. If you were to type an * in the file box you'd see all files and if you then chose an .aa file it would convert it happily (I tried this with a format 2 file).
It's using the default setting on ffmpeg which tries to match the input - so my enhanced files converted to 64k but the format 2 one, which is low quality, came out at 8k. In both cases the file sizes were similar to the original.
I tweaked it a little to change the labels etc to English so I may go ahead and change the file dialogue too. Although I usually always use the enhanced versions anyway.

Thanks for the info. My one-and-one C programming class was back in...jeez, I think in was sometime in the 90s. God knows whether I could have figured any of that out.
All my downloads are currently in format 4. But I can always redownload to get the better quality MP3. I should probably test to see if I hear a difference.
