Has the problem with Betaplayer, WMA plugin/codec and A05 ROM revision been fixed??

WMP10 is driving me mad with its, seemingly, random inability to read some WMA files, inability to map keys properly so i can't turn off the screen, weird playlist interface... i could go on and on.

ps.. the WMA file rejection problem isn't the A05 registry problem as I restored the A05 clean registry after restoring from backup.
