Sorry, it does not look good. The only reference to a W78E52 I can find at Winbond is regarding a microcontroller called W78E52B. Maybe the W78E52F is a special version which can handle DVB demodulation since I somewhat doubt a normal microcontroller could demodulate a transport stream in software. You will have to contact MSI or Winbond for more information. Ralph -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
