My friend help me to bought it from SG while it launch in June.  I just updated the firmware and now support chinese subtitle for ts file.  Chinese subtitle for mt2s still not support.  They claim it will supprt BD-iso from the future firware updating.  There will be another firmware updating release in august which make the player to support True HD sound encoding pass through.  So far it play all the file i have including RMVB so i think is much better than WDTV.  There still have some minor issue for the player but i think the proboem can be solve through future firmware updating.
