Yes. Starting August 2016, HD service (RM26.50/month) will include PVR service on top of it, which is now known as HD+PVR Service, so all customers that subscribes to HD service (regardless of new or existing customers) are eligible to have PVR service for free, including Value Packs customers. With the condition of, you have to change to PVR box. Even if you don't change, you'll be still paying RM26.50/month for HD service without PVR service even if you can enjoy PVR for free. However, Family HD (RM18.02/month) customers are not eligible.
As for the installation fee, it depends on your package subscription. Naturally, for those that paying a lot a month, you are more likely to get free installation for upgrading to PVR. For those who pay not so much like me (under RM100), I need to pay RM150 for PVR installation fee.
To use PVR functions, your STB needs to be replaced to PVR box. The latest PVR box looks like this:

If you wonder, is there any catch? Erm, basically no. But based on what I assume, one of the reason they make PVR as a free service for HD customers is because of the OD feature. You know OD? The advertisement that keep annoy you, saying "Connect your PVR to your home Wi-Fi" and you can enjoy lots of programmes, bla bla bla... Prior to this, only for those that subscribe and have PVR box can access OD feature, and the problem is, the number of customers having PVR box is way lesser than customers subscribed to HD. That's why they want more customers to use PVR box to have access to OD feature. Solution? Make PVR service free for HD customers.
OD can somehow benefit them, because OD contains paid content as well. Let say there is a programme or PPV (pay-per-view) content interests you on OD library, but you need to pay to watch it. So the customer will tend to subscribe it, which eventually you are paying more money to Astro.
And also, by upgrading to PVR box, the advantage for Astro is that, you are committed to stay with Astro service for the next 2 years as your 24 months contract will restart/start. Terminating Astro during this period will incur penalty charges, of course.
It's very bad cannot enjoy PVR for family lite...
