For the last month, time shift function does not work anymore on my XRS 4000. When I select an available show on a channel that indicates time shift available, it lags and lags without displaying any image. I decided to install stub emu pro on my box using the same server and time shift works perfectly... I have the latest release of BuzzTV 4. Before holidays, it usually worked properly. What can I do since I prefer the interface of BuzzTV to stub emu pro?
