Well, it works. Thansk for all the tips. The problem is the batch option. For some reason -b doesn't work for me but -B and --batch do. So, there is no need for "nice" or changing priorities for at. The environment for at is also okay. (well, in my case). Just to make things clear I have attached my test script. It records 2 different sessions, this was just for testing purposes. Oh, the -B/--batch option also solved the problem of lavrec not quitting after the specified time with -t.
I don't know what's wrong with the B and b. Is this just a typo in the source? Thanks again for the tips. Dirk
