Thanks a lot! It works much much faster. Initial station takes 7 secs and another just 2-3 secs. During the channel change there can be hear short time prevoius channel as it is described in the link you provided.No, almost certainly not... but it may be faster if you try this patch:
AFAIK the patch works with all versions of MP from 1.1.x through to 1.7.x, and for the foreseeable future.
