They're up, DBZ 108-117, the first English dubbing.

Going through these episodes, and comparing the original dub with the version on the Orange Bricks and the Dragon Box, shows that not only did they replace the narration (and later reinstate the Japanese score) but they also redubbed a few characters major and minor. I haven't compared the performances. Also I think the BGM placement may be slightly different in some places.

The first R1 release mostly reflects this dub. There was a missing "stay tuned for scenes from the next episode of DBZ" at the end of 114. Also most of the previews are missing. I took all but one (which I didn't have) from footage a contact in New Zealand provided me. The remaining preview is from one of retroccn's rips and is noticeably lower quality (though I attempted to mask it somewhat by equalizing the soundtrack over top of it).
