In case you didn`t know ALBA 103 is multiregion out of the box, and you can bypass the RCE using the digest function, however there is a slight pause during chapter change. however it does have slight problems with Columbia Tristar discs, particularly the Patriot.
ALBA 104 is multiregion, no problems with Columbia Tristar discs, built in 5.1 decoder and is RCE friendly!!!!!
