If you have your heart set on a video LP, though, I have to echo the suggestions for Gix's, which is awesome.
Great link there, thoroughly enjoying the, what did you call it? The reading. If I may...
The first five times I went to Vivec, I would wander aimlessly, ascending ramps, moving from bridge to bridge, ducking in and out of shops, stumbling into the canols, contemplating suicide—I didn’t go on jaunts into the city, I went on expeditions of sweat, blood, and tears. I wouldn’t leave, I’d escape, and once I had I would hack my hand open with a dagger and swear a blood oath to never, ever, ever return.
And then a quest would come up, and I’d have to go back again. And eventually, I etched a map of the city into my brain, inch by inch, room by room, step by painful step. Although I never became fully familiar with Vivec, I did learn to muddle along with a minimum of difficulty, so long as I had access to a map.
Seriously. You think I’m exaggerating, but the actual bloody NPCs have dialogue about how confusing Vivec is. They hang a lampshade on that nonsense.
