Can download the videos directly with a touch of work...
As a person who never does anything the easy way, I found that you can easily ( well easily, but not that easily ) download any of the videos from this site and view them through Flip4mac decoder ( will most likely run in WMP as well but I dont have that). This route wont let you view them on their website ktvb.com, but you will be able to download them to view them.
INSTRUCTIONS:
1) got o KTVB.com and open up a page that has a video you want to watch.
2) after that page loads enough view its source
3) search for the first part of the URL by searching for 'mms://'
it should result with something like... "mms://beloint.wmod.llnwd.net/a125/o1/"
4) get the second half of the URL by searching for '/cgi-bin/bi/video/makeadplaylist.pl?title='
you then take the part directly after the '=' and before the '&'
ie. '/cgi-bin/bi/video/makeadplaylist.pl?title=www.ktvb.com/arsoninvestigation.wmv&adurl="+wmPlayer_adurl+'
take 'www.ktvb.com/arsoninvestigation.wmv'
(for a shortcut, this second half of the url should be in the page url as well.
5) Now put the two parts together, and get the video address
mms://beloint.wmod.llnwd.net/a125/o1/www.ktvb.com/arsoninvestigation.wmv
6) Now this file can't be downloaded easily so you need a specialty program, I use ASFRecorderX, though there are a few different programs that do this. If using ASFRecorderX, put the URL in the URL field and set the client Tool to mmsclient and hit start and it will download it for you into watchable video (note that for some reason on this app for me anyways it always downloads the video to the root directory '/' when using mmsclient tool)
So there you go, its not pretty by a long shot, but it does work. Though it may not be worth it to you to bother with this much work.
Can grab ASFRecorderX from here ...
