Looks to me like the guys (Fentango, Ting & crew) are doing slighly longer release cycles.
Seems to 6th of the month for the last two.
My guess is the bigger ticket items and work on Blue Ray updates/features is taking the most amount of time at the moment and they are focusing more on this.
It kinda makes sense when you look at the posts on this forum, yes there are still some bugs/issues but for the vast majority of users (and those that have been using DVDFab a while), it does what people need for DVD's, so the program needs to be updated with Blue Ray in mind.
For many including myself, I don't use Blue Ray (yet) and it's a good thing that these guys are in early enough now, before it get's pushed more and more in the public domain.
I know there's other softarware out there that does Blue Ray but for me I love DVDFab and until, the vast majority of consumers start to switch and hardware comes down in price --- think the guys @ DVDFab have got the balance about right.
On the home TV front I'm not HD (or even flatscreen), I don't have any BlueRay standalone and have just started seeing BD Rom drives from PC's at around $110 so for me not a problem to wait a while.
All this said and whilst it's focused on BD alot --- the releases that have come out are still addressing things for DVD but in my mind seems a more controlled process now.
