More information is needed -- frame size, frame rate, codec used, quality level, and data rate settings, etc. There's no free lunch here. Uncompressed video is upwards of 30 MB of throughput per second. Obviously compression and real-time decompression is how video streaming is being done now. The local hard drive can deliver full-frame, full-motion video using some compression, the artifacts from which are noticeable to the trained eye. For CD-ROMs, DVDs, and web streaming even more compromises in quality have to be made. Newer codecs, such as Sorenson and the MPEGs (1, 2, and 4) have changed the trade-off curve, but there are still trade offs to be made.
