    Im getting a receiver which has (110w DIN) output and 65w rms output.Whats the difference?

    they are different measurements of power (watts)

    They are different ways of measuring the output power and providing a means of comparing them (to other equipment measured in the same way).

    (DIN = Deutsches Institut fuer Normung / German Institute for Standarization
    RMS = Root Means Square, a mathematical function)

    I would say the RMS value is more usefull - given it's quoted at 8 Ohm, over a frequency range of 20Hz-20kHz and with a reasonable THD.

    Sometimes output power is quoted at a different impedance (e.g. 4 Ohm), a fixed frequency or at a THD of e.g. 10% - which is missleading at best (can't put the 'right' word since swearing isn't allowed ;) ) ...
