Nebula TV card - which graphics card?



Is anyone using this Nebula DigiTV card? With an ATI graphics card?

When watching TV and there is a slow pan does the picture not pan smoothly and jerk ever so slightly?

I am using a Geforce 6600GT and when panning the picture is not smooth.

I am trying to figure out if it is the graphics card.

Apart from this the picture quality is superb.

What refresh rate are you running the graphics card?
For smooth pans with PAL video it should be a multiple of 25Hz
i.e. 50Hz, 75Hz or 100Hz.
If not then the software has to do a frame rate conversion and you will notice jerkiness.

I've experience similar with DVD playback and the ultimate solution is to use a program called ReClock but I am unsure if that works with live TV. I am sure someone else will give you a definitive answer on that.

ReClock Home Page

There is a readme.rtf file that comes with the 1.4 Version that explains the problem and solution it's worth a read.

Hope that helps


I am running it at 60hz, but only because my Sharp TV LC26GA4E I think is locked to 60 hz.

I don't think I can get it to display 75hz or 50hz. I have tried but failed.

Unless someone can advise otherwise?
