Ok, falling behind on updates (8 behind on the videos and the audio version is well behind).
For video, this is because I switched over to using Nathanpc's server to provide videos (with permission) and it appears that they are not being updated now.
For audio, this is because Nathanpc was not doing audio versions at the time I switched, but by linking to his videos my updates could be done in about 10seconds, so I didn't get around to doing mp3 conversions.
What to do?
I have two issues which need help if we want the podcast:
1. Someone needs to grab the videos/audio
(I don't have access to youtube at the times when I would normally be able to do this). Although it sounds time consuming, I do have some tools available which will automate this process, so it'll be a case of pressing a few buttons and it will get the new files each time, and update the podcast feeds. Aside from uploading/downloading times, the user action required is minimal. No doubt with a little more work it could be streamlined further.
The files have to sit somewhere where they can be downloaded, clearly you will need to have a few Gb of space (only really need to bother with the new videos as the links to the existing ones can stay while they work, typical video is about 40Mb). Also will need to have direct links (i.e. not like megaupload or rapidshare where captcha are needed or box.net where links are not predictable - dropbox public space works and the numbers of downloads are low enough not to be an issue).
So if there is interest, then let me know, otherwise I'm not sure if the podcast will continue or not, at least in it's current form.
