Judging by the level of interest in our release-date post, a lot of you are keen to get your hands on a copy of Planet Earth II. For a limited time, you can score 20 per cent off the sticker price of the DVD, Blu-ray and 4K UHD at JB Hi-Fi. Here are the details.

Dear Lifehacker, I just wanted to know why with Blu-ray discs, some of the are softer than the others. As in, when you slightly bend them they are more flexible. Some discs even feel flexible when you hold them in your hand. Does this mean that some Blu-ray discs are higher quality than others?

Attention Blu-ray fans: JB Hi-Fi is currently selling three new-release Blu-rays for just $30. The deal includes 4K and 3D Blu-rays which cost up to $45 a pop when purchased separately. Bargain! Here are our picks.

4K TVs are becoming cheap and ubiquitous enough for everyone to buy, but that doesn't necessarily mean you need to start watching 4K Blu-rays. This video shows the benefit you really get from those.

If you have a new (and probably quite expensive) 4K HDR TV, then 4K video is amazing -- it looks incredible. But to watch a 4K Blu-ray, you need a 4K Blu-ray player, which can set you back quite a few hundred dollars more than regular Blu-ray. If you do want to make that investment, though, the cheapest 4K Blu-ray player actually does a lot more than just play movies. You can buy a 4K-toting Xbox One S for as little as $349, a full $200 cheaper than the least expensive Blu-ray player on sale in Australia today.

If you've picked up a new 4K TV you're going to need a few more things to get the most out of your TV. Fortunately, you can get everything you need with this guide from RealOrFake4K.

Physical entertainment is on its last legs -- and they're getting gammier by the month. Before we know it, DVDs and Blu-rays will have gone the way of LaserDisc and VHS tape. To the streamers and torrenters of the world this will be viewed as no big loss: they think it's an obsolete format that's overpriced, prone to scratches and less convenient than digital downloads.

But not me. Here's why I'm sticking with discs to the bitter end, and why you should too. (Also, get off my lawn.)

Attention GoT fans: JB Hi-Fi is currently selling Game Of Thrones seasons 1 through 5 in fancy steelbook editions for 25 per cent off. You can also get the same deal on special editions for each season and the complete box set. Bring your gold dragons!

When it comes to movies and TV shows, physical media is definitely on its last legs. For traditionalists, this just means that prices have never been better! JB Hi-Fi is in the midst of a massive clearance sale with more than 350 DVDs and Blu-rays going for under $10. Here are 50 hand-picked titles that everybody should have in their collection. To make life easy, we've also included links to each deal.

Dick Smith is throwing a massive clearance sale this Saturday across all hardware categories -- including 80% off big-ticket items. Yep, Christmas just came early. Here's a look at what you can score on the cheap.

Dear Lifehacker, since January of this year I've been looking to buy an external Blu Ray burner so I can burn Blu-rays and DVDs to watch on my TV. Every site has their own "Top 10" but they're all different. I'm not looking for the greatest, but at the same time I don't want to spend 20 bucks on a piece of junk. I'm on an iMac that's only a year old -- so it's not an outdated paperweight.

When I rip my Blu-Ray discs for my home theatre PC, I'm always debating whether to rip in 720p or 1080p. Can I really see the difference?

Hey Lifehacker, Back in the day (2010!), I could go to my local Video Busters and rent a new release Blu-ray for $3. I could browse, select my movie, and watch it that night. Life was good.

The fourth season of HBO's fantasy TV series Game Of Thrones finally arrives on DVD and Blu-ray this week. We take a look at the different versions that are available, the special features on each disc and the cheapest places to pick it up locally.

The Australian Home Entertainment Distributors Association (AHEDA) has released its market data for 2014. In a trend that will surprise few Lifehacker readers, physical disc sales continue to dwindle. What's more surprising is that the decline was roughly identical in the Blu-ray (BD) and DVD categories. Could the era of Full HD physical media be almost over?

While it's not particularly difficult to rip Blu-rays or DVDs, it's technically illegal to do so in Australia. Disc-2-Digital is a service that creates legal, cloud-accessible versions of movies you own on physical media -- but you'll pay for the privilege.

Hey Lifehacker, I would like to know what the law says about this situation: I bought a Blu-ray disc and now I want to make a digital copy of it so I can put it on my home media server. Is it illegal for me to download a copy of the movie, even if I have already bought it?

I consider myself a little unusual as I purchase DVDs and Blu-ray discs. Some I have purchased recently proudly state on the packet DVD+UltraViolet or BluRay+UltraViolet. What is UltraViolet, and why should I care? As it stands, anything I want format shifted I do with HandBrake, and my home bandwidth means streaming isn't really practical.

Sometimes when you're repurchasing a cherished movie on Blu-ray which you have previously owned on DVD and which your parents once taped for you off the TV, you wonder whether it's worth the investment. This video -- showing the picture quality differences for the recently-issued Blu-ray of 1979 classic The Muppet Movie -- shows us that there really can be benefits in upgrading.
