Do DVDs and LED/Plasm/LCDs still have this red limitation?

No - The red limitation was, AFAIK, a CRT issue only. I'm trying to find a scientific or other article to verify this, but I haven't found one.

Unless you are remembering "NTSC Overheat", which is actually a problem with reds and yellows in a composite video signal. To be broadcast safe, the voltage level (measured relatively as IRE) should not go above 120 or below -20. The maximum white level is 100, but because a composite signal has the chrominance and luminance combined, a 100% saturated yellow would cause the signal voltage to go too high.

This is why color bar test patterns are typically 75% saturation.

The best explanation I could find comes from the DVD-lab Pro manual:

In theory, still a problem if you have a DVD player hooked up with a composite connection. Should no longer be a problem with component or HDMI.
