Using DVD players with older sets

[AUdubon5425]

Hi everybody,

My DVD player died, and I plan to purchase a DVD recorder so I can dub many of my recorded VHS tapes that are starting to degrade.

My plans are to eventually replace the 27" Durabrand TV in the den with a color console set from the 60's or 70's.

I remember having trouble watching some VHS tapes on my '75 Quasar - the picture would bend at the top of the screen. From what I understand, I should not have picture quality problems if I run a DVD player through an RF modulator. Can anyone confirm this?

Also, although I have a Philips VCR that I'm quite happy with, I am thinking about buying a VCR/DVD recorder combo to avoid those picture quality issues.
Is there any particular brand I should avoid? I haven't heard anything one way or the other on the quality of these combo units.

Thanks,

Ryan
