Video Node Stream Error

We are Tudip Technologies, from Pune India and we are working on a Roku Screen Graph Application of playing ISM Streams.

    We have created a video node to play the live stream using following details:

• Stream url: "http://192.188.183.97:1934/liveedge/smil:cbs_hd.smil/Manifest"


• StreamFormat: "ism"


• SwitchingStrategy:"full-adaptation"

    
   The stream plays but many a times it throws out these two errors and the video freezes:

• An unexpected problem (but not server timeout or HTTP error) has been detected. -3


• There was an error in the HTTP response.  This could mean that malformed HTTP headers or an HTTP error code was returned. -1

   
    We have been working on Video node from sometime now and have never faced such error.  Please help us out.
