Technical:
Stop saying "We'll have video next week" and then not having it. Do it when you figure it out. Do it when you can do it well. Stop making promises you can't keep. Try just getting the audio quality to be consistent. Consider using real microphones and putting a pop filter in front of them. It's not that hard to make a little effort.
Fade in the outro music and keep it at a level that makes sense for the speaking volume you've established. You make it nearly impossible to actually hear the last words you're saying. Is the music really more important than the podcast?

Men will sometimes answer a woman's questions by looking at the man standing with her for two reasons. First, they tend to assume that the woman is asking the question _for_ the man, who is embarrassed to ask questions. In this way, they're acknowledging the frailty of the man's ego and trying not to make it worse for him. Second, they make the reasonable assumption that the pair are a couple, and they are avoiding staring at the woman. Both of these are unfortunate and inappropriate behaviors. But they're both rooted in trying to show respect to the man, the woman and the couple. Ideally, the response would be directed to both people -- the presumption is that they are "together" in some sense after all -- or just to the person who asked the question, depending on the circumstances. But it would be nice if you didn't assume the worst about people.
Cosplay is complex. You have a large number of people with various degrees of social issues brought into contact with various people, including younger women, who are dressing in ways that are not, in the large, socially acceptable. The costumes are often evocative of characters who are sexually suggestive. The people wearing them are often attempting to explore their personal boundaries. This is not a recipe for stability and harmony. Of course people should behave decently. But it's not entirely absurd to say, "what do you expect?"
When people see something socially inappropriate happening, their general reaction is to allow the people involved to deal with it. There are some special exceptions to this, such as when children are involved. (When someone is beating their kids in public, we don't expect the kids to "solve" that situation on their own.) But _women_ are not _children_. Regardless of what a woman is wearing, she should be able to deal with interacting with the people who might come up to talk to her. When someone dresses in a costume some degree of attention is presumed to be desired. The woman (or man) should be perfectly capable of saying, "Stop, you're bothering me" when needed.
The idea that women in costumes need to be rescued by "noble" men in the vicinity when they are dealing with someone who is being inappropriate is extremely offensive. You are turning womanhood into victimhood. If an actual crime is being committed and physical restraint is required, then that's another story. But a small, frail, costumed women should be able to talk to a large, offensive man and tell him to get lost.
Yes, a number of these men are socially inept and might not take a subtle hint. Some of them will have neurological defects that make it difficult for them to understand that "I'm just waiting for a friend" means "Get the hell away from me you damn creep!". Especially when the woman is wearing a costume that the man associates with his own sexual fantasies and isn't familiar with seeing real people wearing. But none of that makes the woman incapable of handling it. Indeed, she needs to be able to do that and should be expected to do that.
Finally, it was pure tokenism of you to once again have your women panelist speaking at length only about a female-oriented comic book character. Particularly when the male panelists apparently had not read the comic book, thus emphasizing the "for women" messaging.
