" This model of computer does not have a blu-ray drive unless you got a third party upgrade. In this case, you will need to track down special drivers, which can best be done by whomever sold you the drive.

your recorder will normally give you 5 changes at different regions, and on the last region change that is the one that it stays on, although if you you have never changed the region go to> my computer>right click on your dvd drive>properties and on the hardware tab, your hard drive and dvd drive will show, highlight your dvd drive and click properties and click the dvd regions tab and look at the region to see wot its set at, if you still have 5 changes, it should be set at your region one, if there are no changes left you need to search and download a region free dvd programme to allow any region dvd to be played programme

According to the spec. it should be OK. Don't forget to download the drivers from Sony.com otherwise it won't work correctly.

Surely to load XP is a DownGrade. As this notebook is dual core, I would run Vista 64 or better still Windows 7 64.
If you wish to persist with an old system, you require SP3 for XP.That may be available from a software store but is no longer supported by Windows.
Try http://www.notebook-driver.com/laptops-information/acer-aspire-4520-notebook-technical-specifications/ for drivers that you will require to have support from Acer.

Hope that clarifies your situation.

You can upgrade your hdd as big as they make in 2.5 inch format. Just make sure you get a drive with the same format as your old drive or it will not work. Hope this helps.

Yes, there is. Match the type of drive (Serial ATA or Parallel ATA) you get with what you have. Make sure your Satellite sees the drive in the BIOS. For drives larger than 120 GB, recommend operating systems Windows XP (Service Pack 2 or higher) or Vista. Older OS's have a 137 GB limitation (they only see the first 137 GB of the hard drive despite its size).

you may need a ram upgrade. how much ram are you using?
also you may need a graphics upgrade. then it should play fine.

As far as i know thats impossible. Your optical diskdrive is made just for those speeds that you have on it. You cant change the manufacture settings and speed it upp, or make it to an dual layer disk.
Buy a new one whit the needs that u want and replace the old one. Its easy done and its not that expensive.

Good luck to you

Chek wtat is written on front panel
If it DVD-RW it can record only DVD-R blank, if it + so only +R
or DVD-RAM. If it is DVD +/- RW or RAM it can record any disk.
Also chek the speed for you DVD and disk you using.
If you dvd maximum speed for recording is for example 2.7, 4, 8 you should use only DVD with max speed 2.7, 4, 8 or 1-8, 1-16 etc. So they should be labeled the same as you DVD
Good Luck
