AF Cano, many thanks for your answer! I would also like someone to answer why the em28xx driver recognizes my board differently whether connected when booting or after that. And... what does it mean "em28xx #0: preparing read at i2c address 0x60 failed (error=-19)"? 2010/10/13 A. F.

My device was supported under windows xp which I don't have at hands :-( I tried using windows7 which recognizes the device and installs a default driver.

Sorry, my device cannot supply an mpeg stream... in fact mplayer says: Playing pvr://.
