I recently did some research on trying to find an old cartoon id watch on HBO called Delilah and Julius (2005-2008), and aimed to watch the entire series again. I came across one dvd of half of the first season, but that was it. Season 2 has been nearly impossible to find (some TV recordings are on YouTube) Im currently in the process of writing down all the found episodes and missing ones, so far i have a DVD of 13 out of 52.
I contacted the series creator, and he had this to say-
"Unfortunately, no. Teletoon owns all those HD versions, and most likely won't release them. I'm glad you liked it.
It was only the second series that I ever directed in my career, it was fun, a big challenge from the previous production I was directing." (Ron Doucet)
I tried contacting Teletoon, and they sent an automated message back saying they wont help me. Collideascope Digital Productions (defunct) was co-producing the show with Decode Entertainment, neither emailed me back (not sure if i emailed the right person anyways, i think Decode is DHX Media now)
Id really love to find and own the entire series, it was an important bit of my life and despite being sometimes cheesy was a hardcore kids show.
