DM6467 component out-NO SYNC

 I am  working  on an   application based  on DM6467. I need  to display  the H264 decoded  stream on a component display.
The display is not  steady, in the  sense that it  scrolls vertically often, and  the  display equipment   shows  a NO SYNC sign at that  time. I understand that the
the problem is  due to lack of SYNC  signal. But why this  happens only to this  stream? The  stream can be decoded and  displayed in software players.
Any  help   would be greatly appreciated.
Thanks & regards
JK

    this sounds like a video timing issue between the DM6467 EVM (are you using the Spectrum Digital EVM?) and the display.  This would lead to the display not being able to sync correctly to the incoming video signal.  For example, if EVM was outputting 720p, but display was in 1024x768 mode... it is close, but not quite the same; or vice versa, display could be expecting 720p and EVM could bu providing something close to 720p but not quite 720p, you may see an image but the display may have trouble synching up.
