He has released "Backdoor to Buttsville" and "S&S Live On Tour" so far. "Pool Party at Seymore's Part 1" (which is the next Seymore movie chronologically) was already released by Adam & Eve a long time ago, so that doesn't need to be released.
"Pool Party at Seymore's Part 2" is due out later this month (according to AdultCDMovies.com). Taylor has an anal scene in that one. You can probably expect to see the rest of the Seymore/Taylor movies being released on DVD over the next few months.
