I recently tore my entire old setup down which consisted of a Panasonic DVD player with built in DD Decoder, and a Techniques 80 wpc mid-fi reciever, (add various PC/game system connections/a PC using stereo RCA and a run of the mill WEGA TV) , and swapped in a new Panasonic SA-HE100 reciever which would spposedly yeild better sound, and am now running spdif from my PC (Dell Inspiron 8100) w S-video out (limited from the adapter). First off I had a problem in my old setup from my component cables from my Panasonic DVD player to the tv, weather it was the wires/some sort of interference/faulty machine etc, there was a lot of distortion (wavy lines) in the blacks. ( Used all monster cables)..Now with the s-vid out from my PC, the lines are gone, but the picture looks like absolute crap (all grainy; using Intervideo WinDVD on win ME/GeForce2Go-16 meg)..and the sound crackles (yes it does output DTS and DD 5.1 (EVEN tho I'm usinf a 75 ohm gold sheilded monster cable, (it's even directional, and I have it on the right way)). So basically my DVD playing off my PC sucks at the moment, with less than stellar sound and the worst quality picture I've ever seen come from a DVD. As soon as I hook my OLD Panny DVD up through the SAME spdif input, using the SAME cable, as well as the SAME s-vid cable I was using for my PC, I get a stunning picture (for my TV) and superb, crisp sound! This leads me to believe this is a problem from my computer. Should I upgrade The Intervideo Software? Because I get the same crappy quality with that other player that every DVD auto installs, and I get the same or worse quality with winMedial player 9 series, etc.. I don't HAVE to use my Pc to play DVD's, I just want to know what the problem is, so if anyone has experience with this please share it with me so I can at leat know what it is (and ideally fix it). PS: This problem exist no matter the bitrate/freq. being transmitted through the spdif connection - my reciever auto detects everything, so I also do not think that is the problem, however I'm really a novice as is most likely obvious....so any insight is appreciated - even if it's simply that I have a sub-par computer.. -Matt Edit: additionally, I do not believe that Intervideo is attempting to perform any decoding, as I do not think it even has that feature..However please correct me if I am wrong, because I realize this may be the cause..The version is the OEM that came with ME. It does have the spdif option un-greyed and not patched by DVDGenie. Edit#2: I have also tried Minority report : outputs DTS, but very crackley at a high bitrate, Jurassic Park 3, outputs DTS, NOT that crackley for some reason...Uptown girls (not my movie) sound is FINE at a lower bitrate but the picture still looks like crap) Additionally I have tried other various monster, ultralink and even some OEM video cables to no avail.
