hmm I'm anyway sure that what I did is correct. In this case, it's a problem of video recorders.
For example that one on my SGS2 record video to file, but when I stop record, there is no confirm button. So I press back and it return to Locus information - "failed" even that video was correctly recorded. Nevermind - when this "failed" response come back, I firstly check if requested file is recorded and if so, I just add it to the list. You may always delete it within Locus directly.
