    yes, both the DVD video format and dvb video streams are MPEG-2 video compliant.

    I feel inclined to add the following:

    Although dvb streaming video IS mpeg2 compliant....but that does not always mean a uniform quality. Quality depends a lot on the actual resolution being used by the broadcaster. Just have a look at the wide variety of resolutions being used by various broadcaster on HOTBIRD alone:

    544X576
    704X576
    352X576
    480X576
    720X576

    Only last (720X576) of the above list strictly adheres to a full DVD rersolution. When watching live TV...one can find the difference between the lowest (352X576) & highest (720X576) resolution picture. BUT there is still a catch even to this. Spice Platinum channel carries broadcast resolution of 720X576...but the contents of its videos are not of the same resolution...hence you can easily discover that Videos on Multivision are much sharper and vivid despite a lower broadcast resolution (544X576)...just because the contents are of high resolution.

    it is just the resolution which doesnot assure you the quality, a lot of channel like dd , ptv,btv etc still using the old analog cameras and then converting the feed into digital, even there resolution 720X576 but video is realy poor quality.
    a lots of chinese channel have a ctrystal clear video with 544X576 resolution becuase of high qulity digital cameras they use for recording.

    what ever resolution it is, both DVD video and DVB video streams are MPEG-2 compliant.

    add to that the bandwidth they try to minimise on transponders. case inpoint: TFC which has a lot of pixels going on whenever the pictures are fast moving, and the quality is really blurred or faded out. so there is no sure way that a guaranteed full mpeg2 can be achieved via satellite, except when the provider gives you that data stream and really adheres to the mpeg2 standard of broadcasting.

    just to record you will need only a dvd or cd burner but to process (encode, decode, editing) the higher the better.

    to watch & record needs the same resources.
    the minimum i tried PC DVB on intel Celeron 1.7Ghz, with 256 MB RAM and built-on 32mb shared vga. it worked fine and could record also.

    the lower CPU will also work.
