This is a weird one, but it is making my Myth setup not work, so I come
to the masses to see if anyone can figure this head scratcher out.
I have an mfe that was running on an AGP Pentium D system with an Nvidia
6200 card. I was satisfied with that system playing back HD, but I
wanted to use some of the new OpenGL video modes, so I side-graded to a
PCI-E board (same CPU, NIC, audio card, just a new motherboard) and an
Nvidia 8400 card. It booted up fine, saw all the hardware, everything
just seemed to work. Until I tried to go to 'Watch Recordings'. And
there it hung. Eventually it came back with the infamous 'Can't connect
to backend' (I have a separate mbe). Strange. I can ping the backend, I
can ssh to the backend, I can scp files from the backend and they copy
at near wire speed, I can ping/ssh/scp from the database server. I can
mount the backend recordings and play them with xine and mplayer no
problem, but as soon as I try to access the Watch Recordings screen, it
times out. The really weird thing is that Live TV works! I can telnet to
the myth ports on the mbe as well.
In my troubleshooting I swapped the PCI slot for the NIC, no change. I
removed the PCI GigE NIC and used the 100BT onboard LAN, no change. I
disabled all extraneous hardware in the BIOS, no change. There are no
IRQ conflicts, according to lspci. I rebooted my switches, no change.
This one has seriously got me stumped. My next step is going to swap in
a different HD and reinstall a new OS from scratch and see if that makes
Does anyone have ANY idea what might be going on?
