I was looking around recently and I noticed that some of the cheapest DVDs available are put out by companies like Maverick, Future Works, Digital Rain, Forbidden Digital, Destiny Productions, Eclipse, Syndicate, etc.

Part of me doesn't trust these studios at all because many of their productions are 4, 6, or even 8 hour compilations.

On the other hand, some of their titles (such as Ass to Mouth, and Anal Coeds) indicate pretty hardcore content which is to my liking.

So three questions pop to mind.

1) Where do these studios get their footage? Do they film it themselves? or do they buy scenes from other studios? (either things that have already been used or that are being discarded?).
2) How much truth in advertising is there to the video titles from these studios? When they title a 4 hour DVD "Ass to Mouth", does that usually mean that every single scene has Ass to Mouth? or do they just put one ass to mouth scene in and then have the other 3.75 hours be regular boring sex? Likewise, if they say Anal Coeds, does that generally mean every scene has anal?
3) Are there any differences in quality between the studios named above? Are some better than others?

Thanks again for any help you can offer. I really am pretty clueless when it come to this.
