Here are my recommended ratings for the 400/450V capacitor in the primary of the power supply in AV equipment (This does not fully cater for supplies using two 200/250V capacitors, which would be about twice the uF value of a single 400V unit):
47uF-68uF: DVD players (non-IDE loader type), VCRs, set-top boxes (SD or HD)
100uF: DVD players (IDE loader type), LCD computer monitors.
150uF-220uF: DVD recorders, PVR/DVR, CRT TV sets (<=48cm), CRT compter monitors (<17in), LCD/DLP projectors.
330uF: CRT computer monitors (=>17in), CRT TV sets (>48cm).
470uF+: Large plasma, LCD and projection TV sets.
47uF-68uF: DVD players (non-IDE loader type), VCRs, set-top boxes (SD or HD)
100uF: DVD players (IDE loader type), LCD computer monitors.
150uF-220uF: DVD recorders, PVR/DVR, CRT TV sets (<=48cm), CRT compter monitors (<17in), LCD/DLP projectors.
