transcoding settings for iSub

[spookybathtub]

I've been confused by the transcoding settings regarding the excellent iSub app, but I think I've figured it out now, so I'm posting in case it's helpful to others.
iSub lets you set a max bitrate for WiFi and a separate max for Cell. That's great, but it doesn't work by default; you have to make some tweaks in the Subsonic server settings.

1. First, find the iSub player in server settings.
2. Change "Max bitrate" to 256k or whatever you like, because for some reason a setting of "no limit" equals 128k.
3. Uncheck the default "mp3 audio" transcoder. If this is checked, iSub will always transcode to the bitrate you set in step 2, including up-sampling.
4. (Optional) Create a new transcoder with the same settings you usually use, for the input formats that don't stream well, and enable only this transcoder for the iSub player. I included AIF, WAV, and FLAC because I don't ever want these wasting space on my iPhone, even when I'm on WiFi.
