no I meant that you need to just let it run (dumpingto the screen).
you still have the same buffering going on. It is 23 minutes into the
program though, so it did get through quite a bit of it.
Ah yes... I'm being an idiot. Here's the *unbuffered* output up
to where it stops:

Oh, and this is a video-tape transfer (thus the errors in the
stream). It's only got about 6 megs out of 720 megs to go... basically
crunched through the whole file.
CFLAGS = -g -pipe ...
(you don't need to remove the -g when you're done, it will have
virtually no impact on perfromance), besides which, mythtv is
statically linked against libmpeg2.
Again, idiot me forgot to install the new libmpeg2... ldd used the
old one at first. Anyway, here's the gdb:
Program received signal SIGINT, Interrupt.

(note it may stop in a different place). Besides the actual
backtrace, I need you to find process_video (in this case it is #4),
then do:
frame 4 (use the actual # in place of '4')
print state
print *info
(gdb) frame 0
#0 process_video (pktPtr=0xbf8a5f88, decode_pic=0) at mpeg2fix.c:466
466 if(! decode_pic) {
(gdb) print state
$1 = 0
(gdb) print *info
$2 = {sequence = 0x8074278, gop = 0x0, current_picture = 0x0,
current_picture_2nd = 0x0,
current_fbuf = 0x0, display_picture = 0x0, display_picture_2nd = 0x0,
display_fbuf = 0x0, discard_fbuf = 0x0, user_data = 0x0, user_data_len = 0}
(gdb)
I think I'm following... never got much into debugging with gdb.
