I have a haupage pvr-150 and am recording straight out of the wall
cable ( 70 Channels no set top box. ).<br>

I do not have my myth box setup to display on a TV. Instead I just
display on my 20 inch ( 1680 x 1050 ) widescreen monitor.<br>

I have it setup to record 720 x 480 lines. Im assuming that I am
getting some benefit from this setting recording from standard cable.</font></div>

Actually, given that you're pulling straight from coax, you could
probably reduce that to 640x480 or even 480x480. But much of this is
quite subjective, so it's often worth it to play with the settings
until you get something you like. Remember, generally speaking, at a
given bitrate, the higher the resolution, the lower the encoding
quality, as there's more frame to encode. So if there's no increase in
detail going from 480x480 -> 720x480, your encoding quality will end
up suffering for no good reason. <br>
<br>
As an aside, there is one other major reason to capture at 720x480:
it's the native resolution of a DVD. Thus no scaling is necessary if
you plan to burn the content.<br>

That is very true, and a useful point.</div>
