A few of Malaysia's Airbus A330s have Select Plus, with AVOD and video on demand. It is a pretty normal airline AVOD IFE (Audio Video on Demand Inflight Entertainment System) which allows you to stop, start, pause and rewind films on demand.
All the 747s have seatback videos as standard, except for a few of the really old planes which just have old fashioned overhead projection screens: these have mostly been phased out. However, the Boeing 737-400 does not have Select Mainscreen or either version of Select 3000i, and does not offer audio video on demand.
Headphones in business class are good chunky ones, with double 3.5mm pins, however they are not noise reducing headphones
There are three types of Select, but in almost all cases you'll get Select 3000i - however a few older aircraft have Select Mainscreen in the economy cabin, and a Select 3000i Portable Media Player in business.

A portable media player is handed out in business class if you are unlucky enough to have an old A330-300 aircraft on North and South Asia routes.
In in economy Class on A330-300, it's back to the 1980s, with just overhead TV screens. Ths is called Select Mainscreen. There are 15-inch dropdown retractable LCD screens are installed at every 4th seat row in economy class zone.
Going Places Malaysian inflight magazine|
It is actually a pretty decent read, and is professionally put together. There are a series of regular features, including Happenings, with a list of events this month around the world, and Shelf Life with books for the beach. The Trends section shows all sorts of things you would never want to buy.
The bulk of the magazine is taken up with a series of travel articles. Admittedly they are taken from the same syndicated articles that many other magazines use, so changes are you may have read some before, but there are loads of them, typically ten or so, all very well written.
At the back is Navigator with the inflight information. There are pages of information on how to use KLIA, how to get into the country, and how to use your seat. Finally on the last page, there is a very good map of Kuala Lumpur.
