I hope I posted this in the right location. Please move it if I haven't.
Mostly what I need is you all's advice as to whether I'm going about hosting a&v files the best way.

My father has his own domain name and online space. Recently, we have thought of hosting audio and video files (of church conferences and sermons) on his website. I have videotaped the pastos, edited the footage, and now I want to make sure I render the media in the appropriate format.

Video situation:
Currently, most accesses to our website are most likely from visitors with dial-up internet. Therefore, I rendered the video, using Pinnacle Studio, in RealPlayer format, size 160 x 120, and with a target audience of Dialup modem. The result is an hour and 6 minute video file of 16.5 mb.
I am new to the whole experience of hsoting videos and such, so if you all have any advice on the way I am going about things, let me know. Also, if you know of a better format for my video that would benefit my dial-up visitors.

Audio situation:
So I also want to make available the audio files of those videos in a separate download, since I thought that n audio would download faster. At first, I thought I'd render them in .RM format as well; however, whereas Pinnacle Studio does have the ability to render the footage as soley an .RM audio file, the size of the result is much like the size of the video file. For example, a rendered audio file is 16.2 while the video file is 16.5. Of course, this little difference in size defeats my purpose of hosting the audio in the first place.
So I turned to WavePad, opened the .rm file, and saved it as an mp3. Of course, with a bitrate of 128, the resulting mp3 was huge, so I decreased it to a bitrate of 16, and now I'm getting a 5mb file, which is great.

Do you all know of a better way of getting small mp3 (or even .rm audio) files? (For the record, I use the free version of RealPlayer, version 10, and encourage my online visitors to download the same.)

Advice of any kind is appreciated. Thanks for reading!
