Whats your video size and what do you mean by lower end?
320x240 should run on 600-800 Mhz machines.
640x480 and especially 1024 and higher will need much more performant systems as the decompression is CPU side (most videos you are watching today normally are actually GPU decoded not CPU anymore, otherwise a 1280x720 would need 3ghz at least for realtime)
