Live TV extremely delayed

[captainhog]

I have recently discovered gbpvr and I am blown away by the quality of this software. However, when watching live tv I notice about a 10 second delay when changing channels/live tv image. My card is the hauppauge pvr-250 and I know there is a little bit of live tv delay expected with the pvr-250, but the delay in win tv and sage tv is only about 1.5 to 2 seconds. Is there anything I can do to improve this??? I installed all the hauppauge drivers before I installed gbpvr, should I try a different mpeg-2 decoder??? Thanks in advance. Captainhog

in the config app theres an option for under "misc" for "live preview mode" check "use live preview mode if possible", this will playback live tv without creating a mpeg file, just plays the direct source, so channel change takes less than a second. however timeshifting is turned off so you wont be able to pause/rewind until you turn it on, which is done by press the "pause" button. this takes a few seconds to switch over, and only can only go back to the time you switched it on (since thats when the mpeg2 file is created).

Thank you for all the replys. I could not find the option for no mpeg-2 encoding. I also fooled around with the pre-play time and it really did not do much. When I change the channel using my satellite controller or press the guide button I do not see the change take effect on my screen until approximately 10 seconds after I press the button.
