i have a dell gx620 tower with a pentium d 3.0, 2gtb ram, windows 7 64bit, radeon hd5550 video card running a sanyo dp50740 plasma tv. i know nothing in this setup is stellar. but when streaming anything over sd i get terrible freezing, jumping, buffering to the point its unwatchable. ive had this setup for 3 years. in the beging it was fine but now not so much. i really thought the computer was just getting bad. so i was planning on purchasing a new one. but in the mean time i wanted to hook up my laptop. my laptop has hdmi and a core 2 duo 2.4ghz so i hooked it up in place of the htpc and got the same results as the htpc, video very jittery, freezing, making anything over sd unwatchable. i took my laptop up stairs to the bedroom and pluged it in to my sony lcd and everything worked fine. so now im questioning if it really is a pc problem. i have a 50' hdmi cable fished inside the wall. could this be a cable problem. or a tv problem? i just ordered a 25' hdmi to run and see if that helps at all. but could it be the tv? my internet speed is over 19Mbps, and the htpc is hardwired to the router with cat 5e cable. any other possible solutions

I believe this is a TV problem, not a computer problem. Are you having any other trouble besides using it for a PC monitor? I mean as in actually watching TV, or playing a console or anything?

the only thing the tv is used for is the htpc. we use the internal tunner for basic cable but other than that all dvds, movie streaming, everyting comes through the htpc. everything else plays fine as long as its not hd. netflix plays perfect, dvds play with no problem, you tube no issues, but anything 720p gives me issues,

i did order a new one its just not here yet. i didnt know if a cable could actually cause that problem or not. im really dont see how it could be the tv either since that is only used as a monitor.
