Hi everyone.Something strange is happening on my system. I believe to know where is the problem but I would like to have your opinions too! This is the situation: after the last DD trailer, I have the DTS Flying disk trailer. I see the "timecode" led tuning on, after few moments the "CDrom" and "Digital" turn on, CP500 selcts SK5 (Format 11). The trailer starts with NO sound in the theater (and CP is still on SK5, and DTS units is reading normally). It has happened twice. First time I thought that something wrong was happened with DTS and I turned off it for that show. Today when the show went mute I selected immediately a Format 05 to have sound in the theater but I tried to come back to Format 11 at the end of the DTS trailer. The sound was there, no problem. Since during DTS trailer all leds are lighted and SYSTEM blinking, and CD-ROM reading, I believe that the problem is in the CP500. Someone remember that I have some interferences problems with my CP500 that stuck the Video selector in the CP at changeovers. I believe that now this is causing problems with format 11 too. Any suggestions? Bye Antonio

Gordon,Thanks for your help but we have already check the ground of our system. The problem is that we have a radio transmitter near the theater. However, Perhaps this time is not an interference problem. Before DTS logo I have, as Fox requested with Fax, Mail, sheet and more two Dolby Digital trailer: 007 and Minority report. Is it possible that exactly when the DTS try to select the format Dolby try to drop to SR. I wonder this because today I had the same mute at the start of the first show; at the start of the second show I set SR (without auto digital) for that two trailers and DTS started normally. I'll let you know. Bye Antonio

Have you tried running the show with Dolby Digital disabled? If you're using a Cat. 699, 700 or 701 penthouse reader, turn off the Dolby Digital reader and test out what happens if you use DTS as the only digital sound. ------------------

Manny,I can't disable Dolby Digital, but latest shows seems to start correctly just selecting, few seconds before of DTS logo, a Format 5 instead of leaving the 10 until DTS starts. I'll add a piece of black leader (without DD) tomorrow to have Dolby Digital dropped BEFORE dts try to start. Usually I have a black leader before the sound logo, this time, due to Fox requests, I have a DD trailer. Perhaps this is why it never happened before. However: in two different theater we had a similar problem with DTS due to DD before DTS. I didn't know, from this time forward I'll have a black leader before every DTS show. Is it a common issue? Bye Antonio

Yes, that's what I was eventually getting at. I think you'll have it solved by doing it that way. Let us know if the black leader solves the problem. I'm curious.------------------ ~Manny.
