I'm saying "Here's this problem I'm having, how do I fix it?" I don't care
if the problem lies with icecast, liveice, libshout, or whatever. I just
want to stream my MP3s.

MP3s and nothing but.

Yep. Found a couple with a few bad frames and deleted them. Other than
that, nothing worse than a missing ID3 tag or two.

Nope. Load remains at 0.0, although if ices starts resyncing, load spikes
to 7.5 or higher. The skipping and resyncing are not connected, as far as
I can tell.

I've got about a gig and a half or so free. And as far as hard drive
bottlenecks... I streamed from ShoutCast for ages with no problems

As far as I can tell, bandwidth is remaining the same. Interestingly
enough, I have no problems at all streaming static files.

Buffer was at 64k, bumping it up to 512k still skips.
