It does matter if Sonic have discontinued it, because the program is about one version away from being the perfect solution to a common problem.
The interface could do with being standardised (remember folders, no flash, etc.) and a way to make the InterActual player a single executable that didn’t need to be installed before usage. THEN eDVD would be perfect.
I mean, it’s a unique and incredibly useful program. It would be a real shame if Sonic just abandoned it.
