Were making a switch from Amazons CDN to our own servers for streaming VOD with Wowza.
Everything so far is great, but, were receiving complaints from users with set top boxes, in this case the LG ST600 series.

Our site uses JWPlayer 6.3 as the player, and Wowza 3.5 for Linux(Debian) as the streamer.

The complaint is that, NO matter which title our member wants to play, the stream stops after roughly 40 minutes.
He is also not able to just scroll past these, roughly - 40 minutes.

What can I do troubleshoot this?
