New submission from Christian Ebert <[email protected]>:

libx264-ipod640.ffpreset contains refs=1 but libx264-ipod320 does not contain
any reference frame restriction.
There is no clear information out there how restrictive exactly refs must be.
According to my tests anything over refs=2 is unreliable:

But by lack of device I cannot say whether refs=2 works on the ipod classic and
if therefore refs=1 is needed.
Anyway, the ipod320 preset should be at least as restrictive as ipod640.
