General FAQ:

1: What is H.264? What is AVC?

H.264 is the next-generation video compression technology in the MPEG-4 standard, also known as MPEG-4 Part 10. H.264 can match the best possible MPEG-2 quality at up to half the data rate. H.264 also delivers excellent video quality across the entire bandwidth spectrum — from 3G to HD and everything in between (from 40 Kbps to upwards of 10 Mbps).

AVC (Advanced Video Codec), or the full name MPEG-4 AVC, is a video codec (also known as H.264). It is the successor to MPEG-4 ASP (Advanced Simple Profile), which is used by DivX/XviD. MPEG-4 AVC is used by HD DVD, Blu-ray and some HDTV transmissions.

What is this compression?

Compression is a meaning of basically stuffing something big into something of a smaller size. File compression is when you make a big file into a smaller file. This is somewhat done in a way by making the screen resolution smaller to fit on the PSPs LCD TFT screen. Most of your files that are huge should become very small after the compression process. It all depends on if you want a high quality video, low quality video, and the length of the video.

How do I get videos and DVDs onto my video iPod?

There are many ways to get video (either from DVD, iMovie or iPhoto) into your new iPod video, but we will cover from easiest to hardest.

1) Buy them from the iTunes Music Store (iTMS). Seems to simple and it is. Click, download, sync and you are done. You can also subscribe to neat Podcasts like DIGG Nation and NBS Nightly News.

2) Use Quicktime 7 Pro which under the File -> Export menu items has an option for "Movie to iPod (320x240). From there you are a drag and drop onto your iTunes icon in your Dock and away you go. Sure, it costs $30 for Quicktime 7 Pro, but think of all those "movies" you can bring with you.

3) Use a program like iPod Video Converter or DVD to iPod Converter which are shareware, a little more difficult, but you can rip DVDs or other video file to the format of your iPod video.

Remember that the law isn't always on your side so be careful of what you rip, who owns it and what the is allowed under the law for personal use.

Why is the usable space on an iPod always less than what it says?

This is very common when it comes to hard drives. You buy a 120GB (Giga byte) hard drive and when you have formatted it, you only can use about 116GB. This is really just a math problem and the difference between the way the hard drive companies measure them and what you see on the OS. From the very good Apple Knowledge Base article.

"Most hard disk manufacturers measure disk size this way: 1 MB = 1 million bytes (1000 1000). A 5 GB hard disk, therefore, is one that holds 5 billion bytes. Computers, including the Macintosh and iPod, measure disk size this way: 1 MB = 1 048 576 bytes (1024 1024). The difference in these two calculations is what causes the drive to appear as 4.6 GB on a computer, but actually be a 5 billion byte hard disk."

My iPod won't mount. It doesn't appear in iTunes or on my computer as a storage device.

First ensure the iPod is connected to a high-powered USB 2.0 or FireWire port. Try reconnecting it to a different port and don't use a hub or chain connection. Slide the Hold switch on and off. If it's still not mounting try the iPod Disk Mode.
