http://udpcast.linux.lu/cmd.html states that --nosync is the default when writing to a file or a pipe, but this does not appear to be the case; I verified with strace that udp-receiver open()s its output file with O_SYNC unless you specify --nosync.

Hello George, how's life? Sorry for the slow response, I've been somewhat busy lately.

I just checked, the current version (20071228) on http://udpcast.linux.lu does not exhibit the problem.
However, I noticed that for some weird reason (K)ubuntu, even 8.04 includes a very old version 20040531-1 which does indeed have the problem that you describe.
