[mythtv-users] Mythtranscode Segfaulting

Ok all...

I need a little help... Mythtranscode is segfaulting over 95% of the time...
I was able to invoke a manual transcode similar to what I expect Mythbackend
is doing... and ran it through strace... this is what I came up with:

strace -f -o /home/sidrew/my.out mythtranscode -p 29 -i
/mnt/video/1003_20070401003000.nuv -o /home/sidrew/test.mpg

2691  gettimeofday({1175482558, 466483}, NULL) = 0
2691  read(9, "A3\0\0\330\n\2\0\200\1\0\0", 12) = 12
2691  read(9, "\377\373\224\4\0\17\362;#\322\3k\32PJd\212 at m\203J\n\34"...,
384) = 384
2691  read(9, "V4\20\0p\n\2\0\31\27\0\0", 12) = 12
2691  read(9, "\0\0\1\266TM\301\347\352d\344\312\356\351\324\221\303W"...,
5913) = 5913
2691  futex(0x8133e54, 0x4 /* FUTEX_??? */, 1 <unfinished ...>
2695  <... futex resumed> )             = 0
2691  <... futex resumed> )             = 1
2695  futex(0xb68c7e64, FUTEX_WAKE, 1)  = 0
2695  gettimeofday({1175482558, 469285}, NULL) = 0
2695  clock_gettime(CLOCK_REALTIME, {1175482558, 469315989}) = 0
2695  futex(0x8133e54, FUTEX_WAIT, 31373, {0, 99969011} <unfinished ...>
2691  futex(0x8133e54, 0x4 /* FUTEX_??? */, 1 <unfinished ...>
2695  <... futex resumed> )             = 0
2691  <... futex resumed> )             = 1
2695  futex(0xb68c7e64, FUTEX_WAKE, 1)  = 0
2695  gettimeofday({1175482558, 469428}, NULL) = 0
2695  clock_gettime(CLOCK_REALTIME, {1175482558, 469452920}) = 0
2695  futex(0x8133e54, FUTEX_WAIT, 31375, {0, 99975080} <unfinished ...>
2694  <... select resumed> )            = 0 (Timeout)
2694  select(8, [5 7], NULL, NULL, {0, 10000} <unfinished ...>
2691  --- SIGSEGV (Segmentation fault) @ 0 (0) ---
2696  <... futex resumed> )             = -1 EINTR (Interrupted system call)
2695  <... futex resumed> )             = -1 EINTR (Interrupted system call)
2694  <... select resumed> )            = ? ERESTARTNOHAND (To be restarted)
2696  +++ killed by SIGSEGV +++
2695  +++ killed by SIGSEGV +++
2694  +++ killed by SIGSEGV +++


This was the last few lines of the output... I have no idea what it means...
but surely someone will know... please help.

Thanks,
