Ok with this said let's go check the main hardcore teen videos; the video pages are quite detailed in fact on the main page you have detailed info about how to download the videos and they have both low and high quality videos available plus from the video pages it's easy to reach the photo gallery of that set just by clicking the link 'view photo gallery'. When it comes to the photos, they have quite small thumbnails and the quality of the full sized images look pretty good plus I like their navigation system in fact it's really easy to jump from one photo to the following one, just use the thumbnails located at the top of the page.
Back to the main page of the members area, I also have to add that some (not all all) of the videos are available in HD, you will notice a small graphic at the left of the screen, I have checked out some of those and they are looking very good, in 16:9 format mostly. Buffering took a while but in the end it was worth the wait because once they finished I had a great looking video playing in front of me.
Eventually for the video clips you also have the full movie downloads in .wmv format and keep in mind that those files are pretty large, in fact they are around 400-500 mb in size.
The list of teens available in the members area of Dirty Daddys Girls.com is pretty large and that is definitely a good thing. Plus if you consider the fact that many of the clips are available in HD then that is definitely a plus. Other than that you have also teen photo galleries (no .zip downloads) and a list of Bonus Sites which look pretty good although the other sites did not have as much content as this one.
