I have my computer connected to a dct6412 via 1394 and whenever there is fast motion (even just like Jay Leno walking around) it results in tiling on my computer. I am using VLC to view the live program. The thing is, when this happens my TV (which is not HD) almost stutters, but doesn't tile. I downloaded a sample of a HD recorded video and it played back fine. Is this a computer problem or a box problem. I tried on 2 different computers with the same result. Both are laptops with similar specs, 1 gig of ram, 1.6Ghz processors. Thanks!
