my beagleboard use case

hello,

I read the group to some extent and it looks like experiences differ a
lot, so please let me ask some questions:

I consider building this scenario: a single wifi-webcam, three displays.
The displays are connected to beagleboards. the boards receive the cams
rtsp stream over the air. shell script or cron lets the boards alternate
between displaying live video and local files.

- Can the beagleboard play local mpeg2 dvd-quality (576p) files?

- Can its mplayer or vlc transcode live rtsp: mjpeg or h264?

- Whats the maximum resolution to achieve realtime for rtsp playback?

- Can I expect audio to work?

Thank You in advance.

If you use the DSP this should be doable.
