Anyway, my guide below is based on FireFox but the same logic should apply in IE too without any real pain.
First up, RTe store the smil files for their Realplayer content at this default location
And what you really need to highlight the specific point you've decided is important for your viewing public is to find out the number assigned to your particular show. You do this by going to the show on the RTe site and once you're on the page where you could click on the links to open the slip in RealPlayer, you look up the page source from the browser. This is under the View Menu list as Page Source and it will open the generated source code for the webpage in a basic editor. You then need to search for "showplayer" and you will be taken to an area of the code like this
You can then open the smil directly by replacing the XXXXX below with the number
and hence save it locally to your hard drive. Once saved, make a copy of the file and open the copy in some basic text editor, (for God's sake don't be opening it in Word or you have all sorts of formatting characters making their home in it)
You then search for the place in the code where the RealPlayer protocol rtsp is invoked. Do this by searching for "rtsp", some example code you may come across below
You can see above quite clearly where the clip-begin and clip-end settings are. Those are the time marks from the beginning of the entire clip and you can change those to be where in the actual clip you want your version of the clip to start and end. Save the file and run it to see if it starts and ends in just the right place and once you've got it nailed, save it. Then the more awkward bit you need to store the smil file itself somewhere on-line so that you can link to it. I put my few files on missteps.ie
* still if your team wins in the end what do you care if the preceding 90 minutes were turgid rubbish broken only by lightening and pitch invasions.
I did this myself back when I was electioning because I wanted to draw attention to some of the inconsistency of the views of a particular government junior minster. On the more general pint, I've finally got that TV card and S-Video cable on order so watch this space for much better video commentary in future. It probably won't be Jon Stewart but what is!
Most of the credit for the tech stuff should really go to Braz. He even had some suggested reading which I promptly ignored. All the same though I've included it here in case you're more sensible than I.
