Pinnacle and Dazzle

Is the Pinnacle Dazzle TV-to-PC equipment sold in the UK? I have one here
in the US, and cannot get it to work properly on my compaq nx9010 with
Ubuntu 9.04. I can get a jerky picture, with no sound.
I had it working some time ago on a newer PC, with WinXP, but that is no
longer available.
If anyone thinks he/she can help, I will post more information. I have
exhausted all I can find here, I need somebody who has done it successfully
to help me, and I don't know if this is used in the UK.
