dazhong,

there must be something else going on in the decoder, maybe a old decoder
release will work better for you. how about reverting back to a release
before the real time checks where coded, say release decoders-3.0.1.tar.Z
it is in the ftp directory

at this point this is probably the quickest resolution.
