I've already covered converting files such as AVI/MPG/DVD etc to Zune playable WMVs, but what about all those WMV videos you have that are not in Zune compatible format, I know for a fact certain, more mature

, websites offer nonDRM full size WMV downloads. Want these on your Zune? Read on...
First off, get yourself Windows Media Encoder Series 9, its free and can be found here:
http://www.microsoft.com/windows/windowsmedia/forpros/encoder/default.mspxOnce you have it installed, run it. you will get the 'New Session' box appear...

Choose 'Convert A File' and click OK.
Now you will get the screen to select your source file and destination file...Choose your files and then click NEXT.

At the next screen just choose 'File Download (Computer Playback)' and click NEXT. (We will edit the settings properly in a minute.)

At the next screen IGNORE what it says and just click FINISH. (We will adjust bit rates etc in a minute.)

When you click FINISH, you will be presented with the 'Session Properties' window on the left of the screen. (You may have to click the 'Properties' Icon along the top of the window just under the title bar too make it appear).
Leave the first 2 tabs, 'Sources' and 'Output', alone and go to the 3rd tab 'Compression'... And click EDIT:

You will get this screen:

ONLY change the settings inside the red boxes that i have indicated. This includes the recording mode (CBR or VBR etc), the codec (I find the ones shown work best) and your format, NTSC or PAL (Im in UK so Im PAL).
When thats done, choose the next tab in the window, its usually called '5329 Kbps':

You should have the same settings as I have above for the best results (bear in mind that if using NTSC video your frame rate will 29.97), you may wish to change the audio format but don't go higher than the setting I have!)
The last thing is the box called 'Video Smoothness'. For general movies/tv shows '50' gives a good balance between sharp and smooth, but for sports (like my MTB videos) i use 75 to keep it on the sharp side. Up to you really.
When done and happy, click OK.
Your settings should now be displayed in the 'Details' box:

Everything is now set, the other tabs are fine we don't need to change anything, so just click APPLY and your settings will become the current encoder settings.
Now is the time to save your project as .WindowsMediaEncoder to save the settings so all you have to do is change the source file each time under the 'Source' tab. Or you can just change the settings each time, up to you (depends on how much encoding with it you will be doing).
Now you are ready, click 'Start Encoding' up near the top of the window:

The window at the bottom of the screen will give you all sorts of info while it encodes, including estimated duration and such like. Your video will also play through in the preview windows, so you have some idea of how far you are to completion.
Thats it! Hope it helps.
Any problems, just ask.
EDIT: Just noticed a post about 16:9 ratios in Windows Media Encoder, I havn't really tried yet but as long as your source video is encoded with square pixels you shouldn't have a problem as WMencoder will interpet it and preserve the ratio in the output file. Not sure what happens with non-square pixel files, anyone who has tried any feedback?
