there were 2 different Gundam 0079 Movies eng dubs, 1 was from VHS and 1 from (correct me if I am wrong) I believe the US DVDs (which included the 5.1 Jpn audio).
There's only one dub of the compilation movies and those were on VHS. The DVD release does not include English audio. This was probably left off the release over the consistantly bad mispronunciation of "Gundam".
The release of the TV series itself, however, does include English audio but with a completely different voice cast. "Gundam" is pronounced correctly in this dub.
