Not the case at all - InuYasha is a complicated project because a. There aren't lots of materials available (and we often have to chase down more, plus we've been commissioning our own articles to provide more context and discussion of the series), and b. We're authoring each release ourselves to provide the best video quality that we can, which is a particularly painstaking task on this one.
Ultimately we're as keen to get these moving again as anyone. There was a hold-up in terms of licensing and acquiring the rest of the rest of the series, but that's now done and dusted so it's just about us making all of the required work to get these moving.
