OK, that's a standard chip and supported.

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.
