"I meet a problem when transferring my iTunes movies to USB flash drive. It appears the USB drive can't recognize the iTunes videos correctly? Because it's continuously informing that 'File Format Not Supported' when I'm trying to play the movies on my TV through the USB port. Why? Can anyone explain and suggest a workaround to this?"
This could be a common problem for people who have a smart TV that supports media streaming via USB port. Suppose you have such a USB compatible TV and regularly buy movies from iTunes Store, would you like to watch your iTunes movie on TV using the USB flash drive? I guess the answer is "yes". In fact, if you already downloaded the iTunes movies to your computer, you can easily transfer the videos to any USB flash drive, like you do with other video files. However, if you connect the USB drive to the TV port and attempt to play the iTunes movies on TV, you'll get the error message which won't let you play the movies properly. That's simply because all the iTunes movies and TV episodes (as well as music videos, and iTunes Extras) are encrypted by Apple's DRM copyright protection. In result, iTunes videos can only be playable on Apple's devices or iTunes app compatible platforms. To play the iTunes movies via USB, you have to eliminate the DRM encryption from the iTunes videos thoroughly. Now follow the guide here to learn how to convert your iTunes movies to USB for playing on TV in a few steps only.

Part 2. How to Remove DRM and Transfer iTunes Videos to USB Flash Stick
Here I will take the Mac version of DRmare M4V Converter to instruct you how to use this powerful software to get rid of the DRM from iTunes movies so that you can transfer the DRM-free iTunes videos to USB flash drive and play on your TV.
Step 1Add iTunes M4V films and TV series
Firstly make sure you have already downloaded and authorized the movies or TV shows to play on your iTunes. Then launch DRmare M4V Converter. Simply drag and drop the downloaded iTunes movies from iTunes Media folder and import them to the main screen of DRmare. Or you can add the iTunes videos via "Add" button at the bottom left of the program.
Step 2Customize output settings
In this step, you are required to select an output format for the iTunes movies. You should make sure the format you set is compatible with your USB drive or TV set. Here I'd recommend the lossless MP4 or HD MP4 as they are universally supported by most of the media devices. Or since your purpose is to play the iTunes movies on smart TV, you can also choose the preset profiles of specific smart TV you own from "Devices" panel. Currently DRmare supports popular smart TVs, such as Samsung, Sony, LG, Panosonic, etc.
Step 3Convert iTunes movies to USB flash drive
Click the "Convert" button in the main interface and it will start to convert your iTunes M4V videos to USB supported formats. Once the conversion is completed, you'll get the DRM-free iTunes movies and TV shows which are no different with other common video files. So that you can freely transfer them to USB drive and play the iTunes videos on TV by connecting the USB stick to the USB port on TV.
Note: While converting the iTunes M4V movies to your USB drive, one thing you need to pay attention to is the format of the flash drive. You'd better use the NTFS or exFAT format instead of FAT32 as the maximum capacity of FAT32 is only 4.29GB for each file, while the other two have no limit on the file size. If your USB is in FAT32 and the iTunes movie is beyond 4.29GB, then you will get error message saying the converted movie can't play well on your TV.
