[MPlayer-users] MPlayer hangs when selecting previous/next channel on DVB

[Giorgio]

Hello,

I just noticed that MPlayer can no longer select previous/next channel
on DVB tv. When I press 'h' or 'k' it fills the terminal with the
message "!!! read_filepos differs!!! report this bug..." and hangs. I
have to press CTRL-C to exit. Has anyone else noticed this? Here's my
command line and the output I get when I press 'h':

Instead, with the following command I don't get the previous message,
but it still hangs and doesn't change channel:
