I have not used FS2Crew but I do have (and love PACX). Pretty neat that I can go on youtube and grab any airline safety announcement (for example Air Canada), convert it to a wav file (freely done online) and then add that into PACX and have the safety briefing play during pushback / taxi etc…
As for the “annoucements” like weather at destnation etc… I make them myself and then you hear it play back over the PA.
