Using free online converter
The first method is using a website to convert youtube video to iPod or iPhone for free. Of course, you can also convert other media videos. This is good for you when you only have one file to convert or you can't install the programs necessary for conversion. My favorite is zamzar converter.
You don't even need to download the video file to your computer. Copy the URL of the YouTube video to the box, choose the format you want to convert youtube videos to (iPod accepts mp4 video. So choose the format 'mp4'), and Enter your email address , then click 'convert'. The downloaded YouTube video will be sent to your mailbox after the conversion.

Another free online converter for Mac I like is media convert.
But you can't convert big video files using free online converters. It is up to 100MB. And the quality of the output files is so so.
Using iPod video converter for mac
The Second Method is using Mac video converter software to convert youtube videos to iPod on Mac.
For this you need the following:
1. A video to download.
2. Video Converter for Mac.

Step 1: Download the videos to Mac
1. Find your favorite YouTube video. This step is pretty self explanatory. Be sure to use Safari and search for your favorite YouTube Video.
2. Next, you need to go to 'Window' and down to Activity. Click on 'Activity' to bring up the next dialog box.

3. Once the dialog box has popped up you need to look for the YouTube page among all the page titles and files listed in the window.
4. Once you locate it and expand all the activities going on in the page, look for the largest file size (this is shown in the right hand corner). Most of the files found in a YouTube page are small files while most FLV files are several megabytes.
Once you locate the largest file, double click on it. This should cause another window to open and a download to ensue after that called "get_video".

The downloaded file might be two formats: avi and flv. iPod and iPhone only support mp4 format. So you need to convert the videos to MP4 files.
Step 2: Converting The Video to iPod, iPhone, iPad, etc
Great, now you have located the file and downloaded it to your Mac. What's next? Well, you need to launch your freshly installed Video Converter for Mac.
Click the "Add Files" button to import your downloaded YouTube video files, you can also drag and drop the video into the program. This converter supports batch conversion, you can add and convert several video files at a time.

This process only lasts a few minutes at the most.
You can convert several videos and join them into one files just check 'merge into one file' option. The output file (mp4) is compatible with iPod, iPhone, iPad, Apple TV, PSP and many other digital video and audio players.
