[mythtv-users] Firewire vs HD-PVR

              ------------  (Repeats forever until the backend segfaulted on
memory corruption)

*** glibc detected *** /usr/local/bin/mythbackend: malloc(): memory
corruption: 0x08ec7751 ***
======= Backtrace: =========
/lib/tls/i686/cmov/libc.so.6[0xb4fd7276]

(and BTW, I really didn't want to watch that show, it was just convenient to
use as a test. . . really).

Thanks for any help.

(and, yes, I want to use the HD-PVR and the firewire because I would like to
say "because I can" also)
