HI!

I'm trying to play a video via RTSP, I have the permissions:

<action>access_internet</action>
<action>set_audio_volume</action>
<action>access_shared</action>
<action>play_audio</action>

but when I play (), it does nothing.

It's possible to do RTSP Streaming on Playbook? If not, it's possible any other kind of videostreaming?

The native Youtube App preinstaled do streaming video.

Thanks in advance

Can you post some code? Do you have any debug output?
