I got my first iPhone this week and have been trying out all the apps to see how well they run, and one of the things I tried was downloading a vodcast from the ABC Website to watch.

A Vodcast, for those not familiar, is simply a video which has been formatted, or rendered if you prefer, to a format which can be watched on iPods, PSP Game consoles, Zunes etc. It's the video version of a Podcast.

Vodcasts are great to watch when you've got a spare half hour and would like to catch up with your favourite show, and so easy to carry on your person since most of us have got our phones with us most of the time.

Naturally I wondered if I could make my own vodcasts from my own videos.

The first attempt through Sony Vegas failed, now I'm certain Vegas can do it, it's just a matter of finding out which setting was wrong and fixing it. Then I searched online to try to find out what the settings should be, but this led nowhere... Though I did find a few forums where others were looking for exactly the same answer.

My video players were not going to devulge all the secret information either. But, then I found a program who's sole purpose is to make videos which are watchable on your portable player, whichever you own.

It's called Videora iPhone Converter, and it's completely free, although when you open it, there's ads, including the hated "Secret of a small belly" ad.

But still, it's easy to use.

About all that's needed is to select the device you use, a iPhone3gs in My case, tell it where to save the file and let it rip. I fed a one hour TV show, downloaded from the internet *coughs*, through Videora

I was happy, it installed on my iPhone without any trouble (iTunes won't let you install videos which are in the wrong format) and I watched it, It was perfect, and no lipsync problems either.

This morning I was sent a link to this place, which has further details on iPhone videos, Thankyou @LukethDragon on Twitter:
