<div><br>Scott,</div>
<div> </div>
<div>Yes that sounds like a PVR-150 through a composite connection I'm afraid! Is it a long cable connection? Maybe a short high quality cable will help? (if you don't have that already)</div>
<div> </div>
<div>But yes if you look at that comparison review of a ATI card that I posted you can see the softness of the picture.</div>
<div>There should be some controls you can set in the driver somewhere to tweak colour, sharpness etc, you have to ask on the IVTV mailing list. (There certainly used to be things you could tweak on the Windows drivers if you had the right tool).</div>
<div> </div>
<div>But otherwise, it sounds like it's down to the card. The PVR-150 is a budget product, unlike your old purpose built DVR solution.</div>
<div>And until the likes of ATI give us some Linux drivers it looks like we'll be stuck with it! grrr</div>

<div><br>Yes it looks like v4l2-ctl might be able to provide some useful tweaks for you.</div>
