Go to options on the log in page and you can choose Min, Low, Mid, High, Custom and under Custom you can choose Safe mode, Software, OpenGL®, DirectX®.
Min or Low should take you out of HD but safe mode is the lowest graphics you can go on the game.
The runescape you most likely play right now, the runescape that has HD and gets updated is RuneScape 2 and is already out and has been for quite a while. RuneScape 1 is the RuneScape classic mode, that only members can access.
No.
This is because your computer doesn't meet the requirements needed for the HD standards, the only way round this and to play runescape is to play it in Low Detail.(question has been edited to add more detail. this answer may no longer be valid)
Nothing different from the original game, just better graphics.
RuneScape Classic: 2001 RuneScape 2: 2004 RuneScape HD: 2008

No, due to technical differences, only a HD DVD drive can play HD DVDs.
You are unable to play runescape on a DS.Computer Req's:RuneScape: 512MB RAM, 1 GHz CPU, 128MB 3D graphics cardRuneScape HD: 1GB RAM, 2 GHz CPUVersion 1.6, update 10 of Java Runtime Enviroment.
I believe that you can but same with me it might be the type of computer or the graphics that might not let you use it.
No, it only plays standard DVDs.
Unfortunately, DVD's, by definition, can't play in HD, only 480p.
There should be a "tool" icon located on the Runescape Window, click fullscreen. Plus you can also customise the other settings, when they are lit blue that means they will be hd.
