I was wondering about this all night, but you forgot the animated feature Brainiac Attacks (2006). It featured Tim Daley reprising his role as Superman - the first time in a number of years (Daley wasn't a part of Justice League/Justice League Unlimited). This film was the odd man out as it pre-dated the current series of DC animated features and is generally forgotten about (probably because it was made as a cash grab tie-in for Superman Returns). Also, if memory serves, it had a television premiere before the DVD was released (being the first DC animated feature of any kind to do so).
Interestingly enough, the voice cast not only featured Daley, but much of the other voice cast from Superman: The Animated Series. However, some voice actors such as Clancy Brown as Lex Luthor and Corey Burton as Brainiac are strangely absent. Powers Booth and Lance Henriksen, respectively, took over those roles.
Another odd feature about Brainiac Attacks is that it uses Bruce Timm's designs, but has nothing to do with Superman: The Animated Series and, as far as I could tell, has zero involvement from Timm, Paul Dini, or Alan Burnett (the main team behind S:TAS).
