1. Is to be expected: APE is very processor intensive and the iPods are rather slow (see http://www.rockbox.org/wiki/SoundCodecMonkeysAudio)

I don't understand the second issue, could you please be a little more descriptive?

ups.. duplicate

Is there some way to optimize APE decoding?

-- I don't understand the second issue, could you please be a little more descriptive?
Playing FLAC, then press 'play/pause' to pause playback. Playback stops and sometimes player starts "...seeking..." intensively for some minutes, I cannot stop this beacause keys not responding.

p.s. sorry for my bad english

APE is CPU-intensive because of how it was designed. It was never really meant to be used on limited embedded devices. You should convert your files to another format, as it is very unlikely that APE will ever be fast enough on the iPods.

What do you mean by "seeking"? Is the disk seeking? (or spinning, maybe?)

I've converted all my APE's into FLAC - works fine, problem solved, thanks.

-- What do you mean by "seeking"? Is the disk seeking? (or spinning, maybe?)
Yes, I mean intensive disk reading(spinning). "...seeking..." - this was a string from Mixtape theme.
