FrontPage2003 - Recommendations for digital media solution

I currently run and manage a site for artists - www.dieselhousestudios.com  There is one limitation.  I do not have the knowledge or knowhow to publish short film clips OR interviews OR performance pieces (dance, poetry etc) which is an essential development phase that the site needs to go through. However, I do not want to deviate from a Front Page solution.

Would someone please recommend the best and easiest way to accomplish this task.

Importantly I am trying to;

1. Cater for differing connection speeds of the user
2. Have a continual flowing media stream (no jittery images)
3. Use a common platform for playback (or have a link, say to flash for the user to download)

There may be an add-in for example?
I have also 'heard' that Flash might be the route to go down?
Let me know if I need to upgrade my FrontPage version to allow for easier development

Please advise on;

1. Where I would need to go for any components/add-ins
2. Provide instructions and code for implementation from a 'test' page
3. If I would need to change any settings on FrontPage prior to publication
4. What format I should save my media clips in OR ask artists to send them to me in.
5. What is the best film quality that I could achieve for effective playback at all connection speeds i.e. quality vs. speed issues OR is there a generic solution that would achieve this for all speeds?

Treat me as a beginner in this area (also with coding), so I will need detailed instructions.

I am ultimately trying to have a very straight forward 'user experience' on the website where the use will be able to click on a link/image which will automatically upload/download streaming media in the 'best solution format' (which may by way of an example necessitate downloading, say, flash...but my reluctance is that whilst this may be a good solution, many people in the arts, or who are interested in the arts are reluctant to 'download' things like flash AND wouldn't have the know how or confidence to do this....a generalisation, but one I have formed after 20 years in the arts business)

I am therefore looking for the simplest user experience for my solution, which may mean a complicated task for me?!
