Thanks for responding. My account had a problem or I would have responded back sooner. Anyway, I solved the DSL file problem by just creating a link to the file instead of embedding it in the page, which was the way I had it originally. And yes, the site works(ed) locally with no problem.
I had to change the format of the DSL file to mpg and just link to it; that worked. The moblie phone file is in 3GP; my phone supports it and I can launch it locally on the PC with either Quick Time or Windows Media Player. However, over the web the file gets downloaded as a binary file with weird characters in it. Apparently, when transmitted over the web, the phone or the PC don't now what to do with it.
I'm investigating WML to see if that will work, but my ISP might not support WML files.
Or I really need to find out if there is a way to play your web site video files on a mobile phone. My phone has the WAP browser. I guess I'll have to keep searching for a solution. Thanks for your input.
