I just checked my 8gb Clip with *.32 firmware it lags by 3 seconds at 8 minutes playing a FLAC file.
This product ■■■■■ I would NEVER have bought this thing if I knew about this bug.
There is another bug playing FLAC where if you fast forward it will pop at some point only playing beginning to end is clean.
Then there is the playlist bug where it will not see a file name with a German character.
