Sounds like you may have 2 problems. Firstly your network may not be
coming up properly. You might try putting a script into /etc/rc.local
containing a 'ifup eth0', followed by a 'service network restart'
(Fedora style: or /etc/init.d/network restart) to ensure the network is up.
Secondly, it seems that myth does not like a unit using a dynamic IP
address. The HDHR *will* take a static address (it's in the forum
somewhere) Been so long I can't remember how I set the unit's IP
address. Or you can effectively make a static address by limiting the
DHCP range which the router is allowed to serve, or designate the IP so
it is effectively fixed. (Netgear routers allow you to reserve IP
addresses against MAC addresses.) This makes the unit effectively
static, and you can put that static address into /etc/hosts.
Apropos that. make sure that you do NOT have MAC address screening
turned on, on the router, and make sure that the router can serve up a
DHCP address...It's easy to set a limit of 3 or 4 DHCP addresses and
then add a bunch of hardware, so that the new one cannot connect (and
*never* will, and will *never* produce an error message beyond 'network
unreachable'...real hair-puller of a problem.)
I got the 12#0 output too and ended up fixing it with phpMyAdmin by
database spelunking.
