A video recorder has the bandwidth to record this but there are two main problems I can see.
1: On all tape based recorders the recording isn't continuous. It has a disturbance or dropoout once per field. On broadcast grade recorders the recording can be continuous but it will be very much geared to the video waveform with its sync pulses and blanking intervals.
2: The dynamic range of a video recorder may well be marginal.
If you digitise the signals with an SDR the problem becomes one of data capture. I would guess that any reasonable PC can do this.
