Lite-On LVW-5115 vs. Philips DVR72?

Hello from a newbie!
I have an old Philips DVR72. It does DVD+R at 1, 2.5, 4 and 6 hours.
I got a Lite-On LVW5115 from Costco for $90.
The Lite-On does +R and -R (a plus for some family members).
The Lite-On has only RCA video in while Philips had SVHS in.
I am burning from a DirecTV Tivo.
My question is, does one have a better MPG encoding vs. the other?
I would suspect the Philips would get a better image from the SVHS,
but I did the same 1 hour show to both and did a screen grab from
PowerDVD on my laptop. It looks like the Lite-On made a smoother
image?
Any adivce? Keep the Lite-On or return?
