Have been running a R5C7 system successfully. It has a 2.4G p4 512Meg mem and 250G HDD. It also has a PVR-250 & PVR-350. This I have made into the Master server. I just created a slave R5C7 which is an old VIA VPSD 1GHz from an old interactTV telly box. I put a PVR-350 into it for local tv viewing. Everything works fine on both the master and the slave. I have been used to http streaming programs from the master with the streamtv option in the mythweb to my IPAQ 4705 PDA running TCPMP. This also works great. The issue is with the new slave. Since it is a slave and not running the mysql daemon I do not have access to stream programs that are recorded on the slave via the slave mythweb interface. Programs it records are stored locally on the slave HDD in /myth/tv.
I can select the program from the master streamtv interface however it errors with :
[00000217] main input error: no suitable access module for `myth://192.168.1.15:6543/1005_20060918154200.mpg'

Command line:/myth/stream/mythstreamtv.sh 'DIV3' 'mp3' '500' '128' '1' '25' 'http' '' '' '[b]myth://192.168.1.15:6543/1005_20060918154200.mpg' > /myth/stream/log.txt 2>&1 &[/b]

A successful stream from a program on the master is :

Command line:/myth/stream/mythstreamtv.sh 'DIV3' 'mp3' '500' '128' '1' '25' 'http' '' '' '[b]/myth/tv/1002_20060918154100.mpg' > /myth/stream/log.txt 2>&1 &
[/b]

Looks like the issue is the way the file on the slave is being referenced for streaming.
