I posted this problem earlier in reply to another posting on\nsimilar lines but never got any answer; so I am repeating it\nhere in the hope of catching the attention of someone who\ncan help. I note that Chris Lanier has helped out a lot in\nthis newsgroup and wonder if he can offer some advice. I\nwill be obliged for it. Whenever I play .avi files on my PC,\nthere is always a lot of jitter and the play is never\nsmooth; but the same videos play perfectly on my Laptop. My\nLaptop shares my PC's files through a wired LAN. The Laptop\nhowever is not affected although it shares the modem via the\nPC through a crossover cable. I have even tried playing the\nPC's .avi files simultaneously on the PC and the Laptop with\nthe same result: jittery on the PC and fine on the Laptop.\nThere is no problem with non-avi video files. On both\nmachines I use Windows XP Pro and Windows Media Player 9 and\na host of codec files which came in a pack with K-Lite Codec\nPack. I have all the video files stored on my PC's hard disk\nand find it very irritating that I can play them smoothly\nonly through my Laptop. I suspect that the root of the\nproblem may lie in the fact that my PC's broadband modem\n(Fujitsu FDX310 USB) is a bit power hungry, and this affects\nthe performance when I play highly compressed avi files,\nirrespective of whether the broadband connection is active\nor not. What is the solution? Any ideas welcome.
