Jerky Live, but fine when recorded+replayed

[amoeba]

I have managed to seyup GBPVR fine on 1 pc, but trying to set it up on another pc and the live tv playback is really jerky. However, if I record and playback something, its fine.

Any idea what I should be looking at? I would have thought if recordings play fine, live-tv should be the same?

Details:
Its a 2.2 celeron, abit sg-72 motherboard, 512mb memory and a 120gb disc. Tv is coming in through a Freecom 'freeview' usb, and going out the dub/vga. I have tried both Cyberlink and Elecard video decoders, cyberlink ones seems less jerky but still far from acceptable.

do you have the "deinterlace" setting in the "Misc" tab of the config set to "encoder passthrough"?

(actually, just thought that this may not apply for your hardware. i am not familiar with Freecom hardware)

Fairly sure I tried all the deinterlace options, but will have another test tonight hopefully.
