Drupal 7.x

I am using the videojs module for HTML5 video playback. Everything is working fine on all browsers I have checked (FF, Safari, IE) and as far as I understand, also on the iPad.
On the iPhone, however, it's not working. The mp4 is converted/encoded using Miro.
Mime settings in htaccess are set as so:

AddType video/ogg  .ogv
AddType video/mp4  .mp4
AddType video/webm .webm

The video embedding is standard code from the videojs module.

I'm new to drupal and I'm trying to add a simple second level of choises in my main menu, and I would like it to be a drop down menu.

I have an "About" menu with three sub choises.
The pages are basic pages and when creating them I choose them to be children of the About menu. However I can not get them to show up either when I hover or click the "About" menu item on any page of the site.

I have enabled the "Secondary menu" in "Toggle display" of "Home » Administration » Appearance » Settings".

I've been using Ubercart since Drupal 5 and really like the system. So when I noticed the UC developers were not getting the love they deserve, I decided to create my own promo website for Ubercart to extend the user base and hopefully attract more developers.

The site is not quite finished and currently I'm in the process of populating it with content in the Modules/Themes/Web Hosts/Dev For Hire sections.

I upgraded my site yesterday to Drupal 7. I have been playing with it in Firefox and it looks great. However, since I am a Linux user I don't open IE often. Today I ran a Windows XP VM to check how my site looks in chrome and IE. Chrome looks great but IE looks terrible. I am using CTI Flex and it looked great in Drupal 6 but somethings very wrong with the Drupal 7 version. Even there demo site looks honorable. Does anyone have any idea on what I can do to fix this. At minimum I would like my header background to show. However, it would also be nice for my text to not be so big to.
