Thanks for that info Nancy.
You should not need Quicktime 10. I dont use it often. I like quicktime 7 as I am on a PC when using AM.
The .mp4 movies with .mov extensions work fine on all of my 4 windows machines. Some running Vista some running Win 7. You are probably correct that I should always record to the H.264 codec as it seems to be more friendly to most viewers.
I am a firm believer in being progressive. Being a Camera operator I refuse to take jobs that are Standard Definition. Luckily not one client in 2009 requested standard def. I didnt spend $10,000.00 on an HD camera to record in SD.
With that said the solution for people in your position is to simply download the tutorial and use "cntrl 0" to shrink the video to half size. In my opinion you should be doing that anyway so you can add the file to your home library in case the site ever went down.
Please dont take my response the wrong way, I am sure its vary frustrating to be unable to view the tutorial. And I mean no disrespect.
I do have problems with most utube tutorials, aside from the lack of resolution I can not keep the video for my own library easily.
I plan to start an paid site for tutorials and those tutorials will be available to view by the lowest common denominator.
