[mythtv-users] Problems with new tunerless slave backend

[Justin The Cynical]

I've searched gossamer and goggle, but I can't seem to find an answer.

Two "machines":

Master backend/frontend - mindflayer
New tunerless slave - zombie  (this one is actually a VM on my main 
house server, it's got the CPU to spare)

mythbackend version: 0.19.20060121-2 (I'm running .19 as the master 
frontend doesn't have the grunt needed to play HD under .20 without 
stuttering, even with XvMC)

/mythtv/storage (drive that holds the recordings) lives on the master 
backend, and the tuner cards all live in the master backend.

Now my understanding is that if a slave/frontend can't access the video 
files directly, it will stream them from the frontend, correct?

If so, I've got an issue and I can't figure it out.

 From the backend logs on the slave:

2007-05-02 03:25:24.216 Attempted to transcode 
myth://127.0.0.1:6543/1010_20070430090000.mpg. Mythtranscode is 
currently unable to transcode remote files.

(The transcode error sounds like I will have to set up an NFS mount, but 
it could just mean that it wasn't able to run the job at that time)

As one can see, the backends are talking to each other just fine, as 
well as the DB, which leads me to believe that the backend is configured 
correctly (there isn't a heck of a lot to configure).

But for some reason, the video data is not making it to the slave to run 
the transcode/flagging job.

Any ideas?  I can set up a NFS server on the master backend, but I'd 
rather not add any thing more to that machine.
