It all depends on the bit rate of the video. If you use 224Kb/sec for the audio and 2Mb/sec for the video, you can put 4.5 hours on a DVD-R. If you use a "normal" bit rate of 4Mb/sec for the video, you will get just over 2 hours on a DVD-R.

It depends! I burn to DVD-R/RW, but +R and+RW are the same in terms of capacity. You can easily fit a 2 hour movie with MPEG2 video and Dolby Digital audio on a DVD-R/+R, as long as you encode it with the right bitrate parameters (audio and video) to get it to fit within 4.3 actual gigabytes. I have encoded some old VHS and 8mm home videos to DVD-R and fit 2 hours with room to spare (2000 min bitrate, 7500 max, 256kbps DD audio). In my experience, the video looks the same as the original videotape. Home video is one thing, commercial higher-quality source may be different.

I have not ripped a commerical DVD and re-encoded it to a writable DVD, so I can't address tradeoffs for re-encoding audio and video. I'm sure others can tell you. But the short answer is still: you can fit a 2 hour (or longer) movie on a DVD+R. I've heard that you can fit 5 or more hours of video on a writable if you use VCD video parameters and 48kHz audio.
