I'm looking for a reasonably-priced DVD recorder that I can re-use DVD's over and over again to record TV shows and watch them later. Would DVD+R's be better, or DVD-RAM discs? I need it to be able to record 8 hours on one disc in standard 4X3 definition. I just want to record "Heathcliff" and "Inspector Gadget" on every morning. I can't watch them b/c I start school at 7:30 every day.

For high-def shows, do I need blu-ray in order to record a 16:9 high-def program (720p)? Or will it work with a regular DVD recorder on a higher-quality setting?

Forgot to mention, it MUST have a built-in ATSC tuner. I need to be able to record one show while watching another.
