Of course it does not work if you try to use gzip to decompress lzop
compressed data (and vice-versa). These are two different compression
schemes, and should not be mixed.
If you consistently use lzop it works.
If you consistently use gzip it also works.

Builtin compression just works as perfect if you use matching
compression on both sides.

In order to make sure, I just tried the two scenarios (Lzop on both
sides, and then gzip on both sides), with a CD image built by
cast-o-matic and both worked just fine (but not mixed, of course)!
