vnsi sends a stream change as the first packet immediately followed by an i-frame. At this time all streams have correct parameters, a subsequent stream change causes no close/open. This might be the reason why vnsi works fine with my patches.
If any stream gets reconfigured on a stream change, player sets caching to done even if it was in pvr caching state. This is the reason why you may observe longer channel switching times. Before you got accidently shorter one because pvr buffering did not engage.

I will provide another patch to prevents pvr buffering to get interrupted. I think that this causes oxm player to stall.
