After reading some other posts about this, I have solved my problem by
piping the files into the gpg command, like this:

To encrypt:
cat 2388.mpg | gpg -e -o 2388.mpg.gpg -r

To decrypt:
cat 2388.mpg.gpg | gpg -d -o 2388.mpg.decrypted

By the way, I successfully encrypted and decrypted large files 3GB, 4.5GB,
and 4.8GB on both versions 1.0.2 and 1.0.2b and both work fine, using it on
FreeBSD 4.1.

Thought others on the lists might find this info useful.
