The "utility" of the zebra's stripes is where you go off track, because you are "assuming" that they have some utility because you saw a TV show that "seemed" to indicate that the herd confused the predator. So, what you've done is commit the Evo cardinal sin (yes, I know you're not defending evolutionists) of "assuming" that what YOU saw "seemed" to indicate that stripes confuse predators, regardless of what the truth was from the lion's point of view, which we can never really know. I could just as well assume that the lion stopped because there was a herd of zebra and the lion couldn't just charge into the herd. Oftentimes predators just wait till a weaker animal falls behind the herd and then they attack, and that applies to other animals besides zebras (I've seen it happen with wolves and elk, which are not striped, as you well know). Perhaps the TV program was just showing what they wanted to show so you would THINK that the reason the lion stopped was because of the stripes, which would "prove" that stripes "evolved" to help zebras survive (a totally silly notion, as if they were surviving before they had stripes, then they didn't need 'em). Until I have more information, I'm an eternal skeptic. Human beings are by nature deceitful and will do whatever is necessary to defend their own biases, and evolutionists fit that bill to a T (yep, so do creationists, but usually not out of deliberate deceit).
So I do not need to invent a story about why zebras have stripes (other than that it was due to alleles for different colored hair, or non-colored hair as the case may be). If the stripes just "happen" to aid the zebras when it comes to being attacked by lions, that's fine, but no doubt there are other reasons zebras die, so we'd need to invent some other excuses for why they're NOT escaping from those threats.
Therefore, if we're going to attribute some survival advantage for zebra stripes, I would include that in the ridiculous evolution story category for sure.
As for antelope having speed and buffalo horns, they still die from predation. Are you going to say that speed and horns developed as survival advantages? The question remains: How were they surviving before they evolved those traits? Evolution requires backward "reasoning." No pun intended (backward), but Buffalo don't have horns on their butts, so no doubt wolves and other predators figured out, "Hey, a good place to attack them is on their butts!" Ok, so now where do we take it from there? Did they then develop flatulence to fend off predators from the rear end? That sounds like a good one to me!
