<div>Ditto what Brian says!</div>
<div> </div>
<div>I used to think my VCR was really good. Until I played it through my new TV.</div>
<div>Then I used to think the PVR-150 was good (Composite Video from an STB), until I saw what a DVB-T card could produce....</div>
<div> </div>
<div>But check the obvious, cables shielding etc Also check your recording profiles particularly the resoultion. I always set it</div>
<div>to full DVD (PAL) resolution of 720x576 and it does OK. But it'll never compete with playback of a DVD!</div>
<div>There's analogue in there! </div>
<div>But for the cash the PVR-150 does a pretty good job! I have read that the PVR-250/350 was slightly better but only slightly.</div>
