The DVD Upgrade is an advanced modification to your DVD player, which adds extra features and enables you to get more from your machine. The upgrade supplements the DVD player and in no way harms the playback quality or removes any performance features of the machine.
The following DVD players are supported by this version of the DVD Upgrade:
Sony DAV-C700 Sony DAV-S400 Sony DAV-S500 Sony DAV-S800 Sony CMT-S9D
Macrovision & CGMS disable
All DVD players have a system called Macrovision built in to the player, which is designed to stop the copying of DVD discs to video. However, this system can have adverse affects on some projectors. For this reason the DVD MOD Upgrade disables Macrovision to solve any problems.
Put your player into „Standby“ Mode and enter one of the following commands if necessary:
Remote control command Function  [ENTER] Default Default region code on the player  [ENTER] Region 1  [ENTER] Region 2  [ENTER] Region 3  [ENTER] Region 4  [ENTER] Region 5  [ENTER] Region 6  [ENTER] Region 7  [ENTER] Region 8 [Arrow down] [ENTER] Only play DVDs with the selected region; auto switching OFF [Arrow up] [ENTER] Default Auto switching ON [PREV I<<] [ENTER] Enable video interference impulses (Macrovision ON) [NEXT >>I] [ENTER] Default Disable video interference impulses (Macrovision OFF) [Arrow left] [ENTER] Enable user operation prohibitions* and access restrictions [Arrow right] [ENTER] Default Disable user operation prohibitions* and access restrictions
* The DVD can no longer prohibit you from using the fast-forward, chapter change or Audio-/Subtitle-/Angle switch. You can no longer be forced to watch intros. Just press [TITLE] or [DVD MENU] and select PLAY.
Here are a couple of the most common reasons for your problem:
Make sure you have selected the right input source on the DAV-HDX275 that your TV station source (cable, satellite, direct TV or whatever you get TV stations from) is connected to on the DAV-HDX275.
Also make sure that if you are using a digital input (HDMI, optical, or coaxial) from the TV station source, that the DAV-HDX275 in set for a digital input and on the right source.
If you are using an analog source (red and white RCA jacks) for the TV stations , make sure you do not have the digital input activated for that source on the DAV-HD275. You need to select the analog option.
You must also be sure that you have a cable, whether it is analog or digital, connected from the cable box to the DAV-HD275.
I hope this was helpful to you, it is always very important to double check all the connections and make sure the stereo is set to the right type of input (digital or analog).
