I saw someone post MEDIAbox (http://www.media-box.org) as a good frontend to use in your carputer. I also know of Cobra (however can only find cobra 1 for lcd, and cobra 2 for tft-lcd.). Are there any other frontend that could do "everything?"

I tried making my own using standard HTML and some graphics editing (example at http://ilovek8e.tripod.com/temp/start.htm). This looks good for a start, but the functionality isn't there. If I set the links to load up their programs (like powerdvd and winamp), Internet Explorer interprets them as being 'downloads' and asks you if you want to save or open the files. Is there a way around this?

Any ideas and/or suggestions are welcome and appreciated.
