Puzzletrain with lots of hints. [Ended] [Solutions posted]

Hello there, puzzlers!

It's time for a puzzle adventure featuring several different levels and types.

To start off I will state that I will not hide any code or links in the descriptions. It's purely based on the images that will be provided. You can check yourself if you think this is a diversion, but it will simply be a waste of your time. :)

First 3 puzzles will be group puzzles, each a puzzle of 10 screenshots and a giveaway. Once the 3 puzzles has been solved the slightly more trickier individual challenges start (6 planned to start with). But I also mentioned a whitelist feature. People that have managed to get onto my whitelist through puzzling prowess or being great guys in general will have a bonus giveaway, and that giveaway will have links to the group puzzle giveaways. In other words they will have a head start to the individual challenges, but they are free to help out in the group puzzles if they choose.

Now, as always, never discuss the individual challenges, but feel free to work together on the group puzzles.

Let's get started, shall we?

Whitelist: How to survive: Storm Warning edition

Group Puzzle 1: Movie screenshots
Group Puzzle 2: TV Show intros
Group Puzzle 3: Horror movie screenshots

Individual puzzles starts here: http://www.steamgifts.com/giveaway/6hIdF/contraption-maker

It's time to up the ante, until I have 5 people that have entered the last giveaway, anyone that reaches it and comments on it will receive whitelist and have a chance at the whitelist giveaway: How to survive: Storm Warning edition. This extra bonus will only be available until the hint for individual puzzle #3 has been given out. Time's up.

Individual puzzle hints:
Puzzle #1: This would have been a lot easier to solve if I hadn't filled the entire image with white.
Puzzle #2: I wonder how compressed a png-file is to reduce it so much in size.
Puzzle #3: If png-files could contain layers, I could edit this one in some other software.
Puzzle #4: It's really as straight-forward as it looks. No hidden tricks, it is one of those tags.
Puzzle #5: Just as straight-forward as the last. Just need to find which specific type of code it is.
Puzzle #6: That's not a barcode.

Solutions:
Puzzle #1:
Puzzle 1 image
The image is not pure white, there's a 1 shade difference on the giveaway code. If you use the fill-tool on the background you can see the code.

Puzzle #2:
Puzzle 2 image
There's a rar-file embedded into the png, if you open it up in winrar you can see a text-file with the code for the next giveaway.

Puzzle #3:
Puzzle 3 image
When editing this file in notepad you can see some photoshop XML-code. The <layer> bit has a 5 letter code that's used to solve it.

Puzzle #4:
Puzzle 4 image
It's a basic QR-code that you can see everywhere, especially popular on advertisement posters and such. Nothing secret about it.

Puzzle #5:
Puzzle 5 image
It's a PDF417 type barcode. Nothing special, just needed to find the right type of barcode.

Puzzle #6:
Puzzle 6 image
Made to look like a barcode, but it isn't. It's binary, black for 0, white for 1. Each binary number is 5 pixels wide. Translate the 40 number binary string to ascii and you get the final code. Notice that there's a 10 pixel white frame around it, so it starts and ends at the black bars.

Good luck!

PS. All group puzzle giveaways are level 1, anything and everything else is level 2.
PS2. All individual puzzles have now been created. Good job on SpaceClick who's been trailing and solving every challenge as I've put them out. Let's see if he can be the first one to solve the last as well, or if sleep got the better of him. Group puzzle 2 and 3 hasn't been created yet, still waiting until I see how people do on the first one to adjust difficulty levels.
PS3. Good job on Starlynk, who was the first one to solve all current individual challenges.
PS4. Group puzzle 1 unsolved screenshots made slightly easier. Group puzzle 2 created.
PS5. Group puzzle 3 has been prepared, but not finished. Need to google reverse check everything and such. It will be horror movies released approx between 2004 and 2010.
PS6. The third and final group puzzle has been created and can be accessed after group puzzle 2 is finished. Once the 3rd is finished anyone can start working on the individual puzzles.
