Well, I'd imagine the shows were probably recorded in 480i max so, not much more than these rips.
I also had a vhs tape with various Chesty appearances on it; I think she was the first 'super sized' pinup I remember seeing. She worked her 'good girl art' shtick pretty well; like big boobs were fun and she was having fun with them.
I sort of miss the 'big glamour' hair of that era, but maybe that's just the nostalgia talking.
