No, you aren't missing anything obvious. NetMD doesn't support putting raw ATRAC1 back on the discs. However, if you would like to test it, here's the unreleased version of WMD, which does support that on some devices: https://testing.minidisc.wiki/b0824780-3c0c-11ed-b994-2c56dc399093/ That is a bug I am aware of, I'll fix it as soon as possible. It's still not fixed in the testing version I linked above.

@BearBoy - Yes - there's a difference. ATRAC3 data is stored in WAV, because the RIFF container (the specification that WAV files follow) allow that to happen. For ATRAC1 I couldn't go with WAV, since ATRAC1 isn't supported by the RIFF container. Instead WMD downloads these files as AEA (an old format that was created by MD Editor I think). Sir68k - another developer of netmd-exploits managed to add the ATRAC1 specification to the matroska file format, and we'll probably also try to do the same with ATRAC3, so that the container format will be unified. I'll soon publish a patch to FFMPEG which patch the matroska demuxer there. AEA files are terrible because it's hard to identify them - they don't have a "magic number", unlike WAVs, so the sooner we switch from them the better.
