So import the sentai version I guess is the best solution. Especially at Funimation prices lolFirst K-On pressing hat several corrupt frames. Second pressing had this fixed, but still used the old Bandai / Madman encodes - and not the recent Sentai encodes. It's also missing some special features that were included with the recent Sentai discs...
Will be interesting to see if HMV do an exclusive slip which seems to be the norm for Crunchyroll movies...
