Have a show I taped in 24 bit. Tracked it and flac'd it so its ready to be seeded somewhere. I also took the 24 bit show and dithered it down for a 16 bit copy. Which should I seed?
To me, it depends not on the bitrate, but the sampling rate... 48K/96K, etc.
Seeding a 24 bit/44.1 recording at 24 bit makes NO sense, since you're only using the extra headroom in the recording process. A 24/48 recording could at least be burned to DVD - higher sampling rates will allow for greater definition, but only YOUR ears can tell you if the dithered/downsampled version can compare to the original.
I always seed at 16 bit - I usually record at 24/48, sometimes at 24/44.1.
