catalogue system with steaming video in item descriptions

I want a catalogue system with each item in the catalgoue displaying the following: 1. Embeded .wmv or .mov file (streamed). 2. Various text-based information. Users must be able to browse thru links in this text info whilst the video continues to play. 3. Ratings and reviews from previous users. 4. Downloadable .pdf files 5. The movie file must be downloadable to a video ipod I also want: 6. there to be a *PRIVATE/secure* RSS feed so that content which meets certain preferences can be fed to a subsribers RSS browser It is obviously important that the database backend to this is well organised and easy for content to be uploaded to it. Please show me examples of your previous work in your bids so I can assess your suitability. Thanks, P
