[QUOTE="mm1352000, post: 697905, member: 82144"] Hi again Thank you for that post Melstig. It helped me to understand things a lot better :) Good spotting :) Yes, it could well be the problem. What you're seeing could be caused by what they call a "race condition". You have three critical things that have to load after resume: 1. Network driver 2. TV Server 3. Tuner drivers The network driver must load before TV Server so that the static IP address is ready for TV Server to connect to again. If TV Server doesn't wait long enough for the network driver to load then the network driver may not have applied the static IP address yet. The tuner drivers must also load before TV Server so that TV Server can detect and use the tuners again. If TV Server doesn't wait long enough then the tuners may not be detected, or they may appear as "unknown". There is no guarantee of the order in which these processes will load or how long they will take. I don't think 2 seconds is long enough though. On a fast computer, I'd guess that 15 seconds would be a minimum. Anything below that and you may find that sometimes it works and sometimes it doesn't, depending on the order in which the OS chooses to do things (which is why it is called a "race" condition). I'm pretty sure that delaying the startup of TV Server should fix this, however you should also be aware that some tuner drivers don't handle going into resume or hibernate well. Tuners with problems often "disappear" (ie. they're not in device manager) or don't function properly after hibernate/sleep. The only solution for that is to restart. If the H7 is one of those tuners then there is nothing we can do except disable sleep and hibernate, however I don't think it is the problem here. We'll see what happens... Please do. Like you say, once you find something that works then we can focus on the things that I can help with ;) Interesting. It is good to know that the issue probably wasn't caused by what I've been doing, but we certainly want to solve this if possible. It *appears* like it is not a TV Server issue so I will ask some other team members for their opinions...

Firstly, the information only shows when the H7 is loaded. The process is: 1. TV Server starts and initialises. 2. Your H5s are preloaded. 3.
