Complete novice at this, - I thought Media Player Classic would do it but read on the codeguide FAQs http://www.codecguide.com/faq.htm that..
"Media Player Classic can only play DVDs on Windows 2000/XP/2003. Playing DVDs won't work on Windows 95/98/ME/NT4."
So can some kind soul advise a cheap or free alternative ? I have seen OEM verions of PowerDVD available but usually a DVD drive has to be bought at the same time.
