After i turn computer on the TV is all working fine, i get off TV and go do something else (let it be computer applications or away from computer, leaving the USB TV stick plugged in). Come back boot up Mediaportal it gives me a message "unable to start timeshifting, unable to start graph" or sumtimes "unknown error". Hypermediacentre gives me a blank screen.
i first thought could be MP TVserver conflicting with hypermedia so i uninstalled MP, but still the same.
then after some reading on the internet some people have said that the Kworld TV stick overheats (it was NOT hot at the time as its been in idle with no mediacentre working) so i tried unplugging it when not in use, but after i plug in it still dont work.
It cannot be the problem @ stick (ie, overheating) because as soon as it stopped working i booted up my laptop and tried there and it works.
the only way i have managed to get it going in this situation is 1) reboot computer or 2) unplug and replug the USB tv stick and open /close hypermedia until it decides to go. I have not managed to get MP going after it decides not to go.
system specs as follows
2GB 677 ram
ATI 4850 GFX
plenty of hard drive space
all latest drivers
