WHat I want to be able to do, is have several client machines (Directors?) being able to record TV. So that I'll be recording FreeSat HighDef my lounge projector TV, recording analogue on the one in the kitchen, whilst my girlfriend will be recording weird girlie stuff in the bedroom. I then want to be able to watch stuff recorded in the kitchen, in any of the rooms. I understand that the core can control and share devices, but I only understand devices to mean disks and plugged in AV kit, such as set top boxes, screen, audio etc. Does devices also include tuner cards internal and/or USB.
LMCE supports this, and this is the way it works out of the box with MythTV. I've never used VDR so I don't know the limitations and it's not clear to me from the reply by totallymaxed. I suggest reading the wiki and/or search forums a bit more. Perhaps someone else can give a direct answer.
BTW - I like my network just fine the way it is and don't want to change it. My wireless ASDL router is my gateway and DHCP server and it currently feeds 4 PC's and 2 laptops. The core will be in a different room to it and the ADSL supply, so running an ethernet lead to it is not an option, neither is making it a gateway. Having said that, I have no issues with having 2 DHCP servers, static IPs etc and am familiar enough with TCP/IP to set up whatever you guys recommend. I inherently don't like the idea of network booting machines. It's OK with thin clients and understand (and actually approve) of the LinuxMCE model for that, but that's for a dedicated LinuxMCE network and machines on it. None of my kit would be dedicated to it and as the lowest machine is a dual code with 4 gb ram, I'd be reluctant to do that.
In the end you will need a LMCE internal network that does not have any DHCP server other than LMCE, and an external network that a second nic in your LMCE core is attached to. All the other stuff that is separated from the LMCE net doesn't matter. Do NOT try to change the IP range of the internal LMCE network, 192.168.80.x. Of course it's best if you follow the guidelines and let LMCE act as firewall/DHCP for everything, but if you want to complicate things that's up to you.
So, hopefully I can get LinuxMCE to do what I want and will not be stuck with MediaPortal and regular reboots!
BTW - This is a good time to try it, as one media centre has died. I've downloaded the install DVD iso and will try it with a couple of machines. I may even be in a position to answer this question myself later ;-)
Thanks for the replies guys, not all forums are this helpful...
Good luck!
