Why can I not play a home-made 24/96 DVD-A on any DVD player?
If it was made using the DVD-Audio spec it is not readable by a DVD-Video player

If I'm writing to the audio, does the playback on a standard machine need to see video to operate?
If you add menus it may.

And furthermore, why does writing audio to the video layer reproduce so easily in any DVD playback?
Because it is in the DVD-Video spec and thus playable on both DVD-Audio and DVD-Video players

Also, is the 24/96 sound captured on the video layer compromised? ...is it identical in quality to what would be written on the DVD-A audio layer?
No DVD-Video uses LPCM* but you are limited to 2 channels at 24/96 on the DVD-Video spec, if you want 24/96 Multi-channel sound you need the DVD-Audio spec using MLP* The sound quality of 24/96 in both the DVD-Audio and DVD-Video spec should be sonically equal. So if you are doing only 2 channels you have better compatibility using the DVD-Video spec, if multi-channel you MUST use the DVD-Audio spec for 24/96.

The differences in Hi-Rez PCM between DVD-Audio and DVD-Video formats

DVD-Audio
6 full channels of Multi-channel sound at up 24 Bit 96kHz using MLP*
2 channel stereo up to 24 Bit 192kHz using MLP* if Surround Program is present. There are some Stereo only DVD-Audios that do not use MLP* but are uncompressed.

DVD-Video
Multi channel is usually Dolby Digital, or dts. But it is possible to have LPCM* multi-channel up to 20 Bit 48kHz
2 channel stereo up to 24 Bit 96kHz using LPCM*.

Terms
*LPCM = linear PCM and is uncompressed.
*MLP = equals "lossless" compression of about 2:1 that is bit for bit accurate, sort of like computer packing. So MLP should identical to LPCM
