Two clients and Live Tuning
I've seen this on occasion but don't know if it really is a defect and I don't have a log handy.
1. Start a UPnP client and tune to a known channel.
2. Wait a while, say one minute.
3. Start a second client and tune to the same channel.
The second client plays back OK, but from whenever the first client started. So if there is a five minute gap between the two, then the second client displays video that is five minutes behind the first. I would expect them to be synchronous.
Have you seen anything like this? I can see there could be a problem with TSB sharing and when the client doesn't provide any range information in the request.
