Well, that picture seems to correspond somewhat to the waveform you are getting, so I'm guessing you are using the scope correctly.
If the tuning is that far off, the AFT may not be able to correct it at all. What channel is your generator output? Try setting the VCR tuner one channel higher or lower - you may be tuned to the wrong sideband of your generator. When the generator is set to channel 3, for example, it also produces a lower sideband with reversed spectrum on channel 2; when set to channel 4, it produces a lower sideband on channel 3.
You can use the video output of your generator into the video input of your VCR and skip the tuner problems.
