Have to click twice to get the picture

So I got my backend and fronty end running for TvHeadend. I am using the TVHeadend HTSP for the client. I notice that I need to choose a channel twice for the picture to work.

First time, all i get is audio. Then I stop it and choose it again. and it works Audio and Video.

Not sure if this is a TVHeadend backend issue or front end issue.

Anyone have this happen to them? Thanks
