Well you're partially right there.
"Do You Remember Love?" is a dramatization of Space War I within the Macross universe. Several characters make references to it throughout Macross 7. It is a movie within a movie, so to speak, as was mentioned.
SDF: Macross mainly takes place between 2009 and 2010. Flash foward to 2040 for Macross Plus, where two test pilots (Isamu Dyson and Guld Boa Bowman) are competing in Project: Supernova to see which company's variable fighter (Shinsei Industry's YF-19 or General Galaxy's YF-21) would replace the YF-11 as main variable fighter aircraft of the terran military forces (which was instated into service in 2030). Many events occur that one really should watch the anime to be clued in all, but ultimately the YF-19 is declared the winner of Project: Supernova and over the next 6 years it is redesigned for mass-production until we see the VF-19 as seen in Macross 7 and Macross Dynamite 7. General Galaxy went back and made some revisions to the YF-21 design and it was ultimately accepted as the VF-22, which we see in Macross 7 and Macross Dynamite 7 as a special forces fighter.
Interestingly enough, there are two versions of Macross Plus... Studio Nue initially planned a movie release, but instead rearranged the animation and created a little bit of new animation and formed a 4 part OAV which showed in a sort of serial status in Japan. Then they went back and created the movie version, in which scenes are portrayed in a somewhat different order but all in all it is the same story.
Macross 7, 2045-2046, centers around one Nekki Basara and his band, Fire Bomber, as they try to use music to inspire pacifism but ultimately end up saving the galaxy through music. Partways through the series the VF-19 makes its appearance as a special forces fighter but not as the main fighter of the fleet. Emerald Force is comprised of VF-19s and there are just 4 in the squadron, with perhaps a couple of spare fighters just in case.
A 30 minute movie based on Macross 7, "Macross 7: The Galaxy is Calling Me!" was released and takes place somewhere in the middle of the TV series. There is also a two-part unreleased TV series episode entitled "Fleet of Strongest Women" dealing with survivors of the female contengent of the Zentraedi fleet who still bear hostilitities towards humans.
After Macross 7, a 4 part OAV based on Macross 7 was released, entitled "Macross Dynamite 7" which takes place after the events of the final episode of the TV series. We get to see some new valkyries in this one, including a special version of the VT-1 as well as the VF-5000.
Macross Zero is hailed as the preview to the original series, but that is not entirely true. In the true Macross timeline, there was no VF-0.... the variable aircraft line started with the VF-X1 which was not transformable but served only as a testbed for the aerodynamics of fighter mode. The VF-1 was the first transformable fighter in the terran military forces. Mkay. Macross Zero takes place circa one year before the beginning of Space War I so thusly 2008. It mentions some things such as the crash landing of ASS-1 9 years prior but it is really far too militaristic, since the world was supposed to be at peace during this time. There is a lot of great action, however, and it is a good treat for those who have felt like the Macross series has gotten too silly lately with Macross 7's overly ambitious focus on music.
Macross 2 was initially released as a 6 episode OAV by Bandai as they were concerned that Studio Nue was not going to release a sequel to Macross, so they decided to take matters into their own hands. It was initially shunned by Studio Nue but later accepted as an alternate universe story. The 6 episodes were later combined into one movie with no change to the animation. It is believed that Macross 2 follows a timeline in which DYRL really occured, but this is a fallacy. DYRL is a movie within Macross and nothing more. Macross 2 accepts SDF: Macross as its origin story and not DYRL.
