I’d look at it this way. You have 80 UHD that you want to rip, and lets assume 60 of them are supported by DeUHD. That’s US$4 a pop on the Lifetime Licence (Std), or $1.2 on the 6mth rental if you wanted to just try it out. Sure, it is gong to take you 30 days to rip those 60 discs! … and who knows what could happen in the 60 days.
Actually, that could be another idea for Arusoft on Licencing. Allow users to “buy” X number of decodes (eg a few $/Euro a disc) with no daily limit, just a per disc price. That may be low enough to entice some impulse buy for those on the fence, with only with a few discs, even those that have hit their daily limit but want to do “one more”.
