[MPlayer-users] Bash vs. sh

[Robin Kluth]

Erik, you're right:

ls -l on /bin/sh goes to dash:

lrwxrwxrwx 1 root root 4 Dec 25  2011 /bin/sh -> dash

I've did some tests with -v (-x is a resolution option?):

Test 1 and 2 with da(sh):

Test 1 and 2 with bash:

The thing is, I can reproduce this with sh now, too but not always. It
happens more rare now :(

This issue seems to be stream related, I cannot check that (the stream is
at: http://mp3.89.0rtl.de ).

Maybe some one find a hint?
