Sweetspot, Dscaler and Powerstrip to Plasma

[Chris OH]

Hi.

I use a Uvem HTPC (Hi Phil) to capture and scale Sky+ to an Hitachi plasma (42PD3000 Plasma TV).

I have tried various deinterlace settings within Dscaler and a variety of Powerstrip settings and I am settled on 1280 x 768 from Powerstrip and flit between auto detect, High motion (Greedy) (I think) and Toms for deinterlacing.

I have been trying for some time to sort out a configuration that i am happy with and for film and the like I don't have a big problem but with rugby I find the picture falls to pieces during rapid movement.

Is this something to do with the resolution or deinterlacing? Reading about 50 v 60Hz scanning I am wondering if I am setting up conflicts which manifest themselves in this way. ie Sweetspot captures RGB PAL 50Hz (I think) and then passes over to Dscaler which deinterlaces and presents a signal to Powerstrip which converts to a 60Hz signal which is sent via VGA to the tuner box of my plasma which does gawd knows what then to the display via a proprietary DVI connection.

Clearly from my post you can tell I am no expert but please, any suggestions no matter how technical are most welcome.

TIA

Chris
