Now:
1. Splash Lite
2. Splash PRO
3. Splash PRO EX
4. Splash TV
5. Splash BD
My suggestion:
1. Splash Lite
2. Splash PRO
3. Splash Ultimate
Splash PRO EX is better to make a separate video-converter like Action! Features of Splash TV put in Splash PRO. Splash BD rename to Splash Ultimate (after all, it can play not only BD, but also the DVD). In this case, it will be easier to orient to versions of Splash.
