Switching StreamFormats on 3.0 - build 2227

We have an application that sets StreamFormat to "mp4" and immediately sets StreamFormat to "hls" and plays a second video. It's 50/50 on whether the second hls video will exit with "msg = An unexpected problem (but not server timeout or HTTP error) has been detected. | index = -3". The rest of the time the video plays as expected.

It would appear that *sometimes" the StreamFormat is not set to hls after the mp4 plays.

This works correctly in 2.9 and on the Roku2 but not in 3.0.

Any ideas?

    I don't know if it will help, but I have found that 3.0 requires a Sleep() to be added in some cases when playing videos back to back in order for the video screen to fully close before opening the new one. That might be what you're seeing. Try adding a very short sleep (like 50ms) after playback ends to see if it helps.

    Yea, I've tried that, even putting a 10000ms sleep. It just that sometimes the HLS video comes back as uninitialized, and since the Roku defaults to mp4 it fails. It's totally random, like I said, it will work 2 out of 5 times. I've even tried setting StreamFormat to "hls" again before the video begins to play, but it still fails.
