i'm new to using the join mgr., when reading the join mgr. help page it states: "Effective with version 1.6.903 Replay Media Splitter can join files together into one file. The media must be of the same file type." However, when i try to join two clips of the same type, i sometimes am successful and sometimes i'm not, i get the message: "different formats or incompatible parameters . . . couldn't be joined." Keep in mind that all clips are in the same format, so my question is, why aren't they able to be successfully joined?? Is it the "incompatible parameters"? if so how does one determine this? I don't see anything pertaining to incompatible parameters on the help page.
