Why is everyone obsessed with channel 3?

Is your DVD player REALLY outputting a signal on chan 3? Is that the
channel your TV sees it on OK (i.e. 61.250MHz)?

There again the channel number depends on what 'zone' you have the card
set to - cable chan 3 is not the same freq as broadcast chan 3 (certainly
not in PAL country, I imagine that NTSC is the same).
