I agree with Thrang, though may companies do the same, i.e. publish updates only upon cause/need/demand etc. Here is some late breaking info on the MX150/151 from someone in Germany, who was having Sat TV issues and reports having just received a new update from Chuck H. It is from May 23 and numbered 1.4RC5, SVN 1:3072. This is later than mine which solved some issues for me back in April. Might want to give it a shot, though it could be a Germany-only fix, so that may need clarification.
i have a german mx150.
