Dynamite 1-4 -> "Emotion" logo before start (boring)
Dynamite 1-2&4 -> music album adverts at end (just some - more or less - boring text)
Encore 1 -> Ads at end (e.g. for Macross Plus Vol.2)
Encore 2 -> Ads
Movie -> Ads at the end (e.g. for Macross Plus English version and a short scene with the singer of Mylene)
FOTS -> some text at the beginning ("Unbroadcast TV Episode - Fleet of the Strongest Women") + 2 pics at end




As for normal eps of the tv series (usually length is lower than/around at 25min and if it was higher there was more):
Macross 7 PLUS (GMM as single file and then at the end of 08, 12, 16, 24, 32, 36, 40, 44, 47)
Special Presentation (live convert scene at end of 28)

New in the mkvs:
* Better quality and softsubbed (therefore higher size)
* Being incomplete in a way (see above)
* Some untranslated text notes at the end of some eps

(#=removed Japanese text)
TV-Japan released some raws and they also once were linked here.
Not sure if the links would be dead now anyway, so 'nother source: macrosshare*com/2008/04/series-macross-7-remastered*html.
If I'm not mistaken, then TV-Japan's Macross 7 commercial raw doesn't replace all the commercials from the old avis of Macross 7 OVAs (Dynamite, Encore) and the movie.
A few lousy transcripts of C-A's subs (and a bit more; if it is ok for you, else you might also remove the link):
