Are you definitely using codecs and plugins compiled for your new 64MB
Rockbox? Codecs and plugins are compiled and linked to run from fixed
locations at the end of RAM - so if you are using a 64MB build with
codecs built for a 32MB build, it won't work.

From what I can see, that should be enough to make the codecs and
plugins work.

Try the following steps just to make sure nothing bad from a previous
build is still around:

1) Create a new build directory

2) Run ../tools/configure followed by make followed by make zip

3) Delete the .rockbox directory and rockbox.ipod files from your ipod

4) Unzip the file you created in step 2 onto your ipod.

But afaik, you're the first person to try a 64MB build - so there could
be more subtle problems.
