Vilodex jumped into the alphabet soup: It has an XML button now that actually features an RSS feed. Since there is not much to read this is only interesting if you give this feed to something that can handle the so called ‘media enclosures’. iTunes 6 can. Ant can as well. There are probably others too.
Media enclosures will make sure that your capable RSS reader will download the latest vilodex videos for you.
You could get fancy and compress them so that they fit your PSP or iPod Video. Probably an automator job.
