Digital TVTuner Player question

[Skyfish]

I am located in the Netherlands where I have Digital Terrestrial (cable) TV, it is provided by the cable company (UPC) through a regular antenna cable which goes into a digital box/set top box (called MediaBox) which then comes out as a SCART connection ONLY! :(

The problem is that I do not have a TV but a Home Theater installation which is a simple PC with a TVCard (a Philips SAA7314)
with no SCART IN of course...

For the moment the only way I have found to watch those extra Digital TV channels is by converting the SCART coming out of the set top box into SVideo and Composite, plugging those cables into my computer and using VLC -> Capture Device to pick the signal.
It works but the quality of the signal is very poor. I know I will never get a full Digital signal anyway (there is no HD channels yet in Netherlands so no matter) but:
Any suggestion on how I could improve on this DIY installation?
Thanks:)

there is no HD channels yet in Netherlands so no matterSeriously!?!
If you get a dish pointed at 28E you can watch BBC HD in the Netherlands. Channel4HD is currently FTV only, but that and the upcoming ITVHD should be FTA later in the year. Of course they are in English, there are probably other European feeds you can hook into if you point the dish the right way, pretty sure there's some FTA German HD. The only other FTA HD service on 28E is Luxe.tv which is rubbish.

Anyway I have a SAA731x and found it to be reasonable, if not excellent. Does your cable box have an RF modulator? If it did you could maybe use that and "tune" into the signal. May be better (or worse).

I have Terrestrial cable remember? No dish ;)

I am happy with the TVCard yes but no the RF modulator coming out does not have the extra digital channel it is just a bridge of the regular cable... :(

Anybody has an idea to get a better picture quality?

I have Cyberlink PowerDirector for example and the quality is quite good when I capture and/or record so it is not a connector/hardware issue as they stay the same.
Why can't I get the same image quality when I use VLC? I tried using MPC but it does not find the device...Maybe there is a better software to view the images coming from your video capture device?
Thanks for your help.

Did you try Dscaler (http://deinterlace.sourceforge.net/)

[Skyfish]

Aha great idea!

I am afraid they do not support the Medion card yet though :(

Thanks anyway!

OK DScaler is working actually but I still have to make it work properly (no sound atm, and image is slow...) Need some fine tuning.
