Checked, the clock is @ 27 MHz.

Yuh, that's commonly used in all DVD and BDP.

咩 transformer spec ?
係transformer, 駛鬼佢比,自己都測量到晒喇!

The spec for internal transformer on the circuit board.

師兄, 邊隻transformer呀?
相中the one? that's a switching transformer.若預備change to 線性power supply, 你根本毋須理佢!
About the p.s., VDigi應是買OEM 匯入塊板照用, 佢engineer知到隻牛spec就奇 !
自己測量到晒d DC voltages, 代入DIY spec, 得喇! usually, 出12V, 5V, 加埋local 3.3V, 至多比埋+\-15V, (摩机)夠用有突.

Tested, it does get quite hot. How can I feed power to a fan?

quite hot ?the CPU or the transformer ?
if u intended to install an auxiliary dc cooling faninto the box, try below...(this would eliminate the risk of overloading the VDigi power module).Drive the fan at 7.5~9V 400ma, typically, be quiet and cool !
<< FYI only.
better to use linear power module. adjust the 7.5~9v output for optimization.
