TVIP 605 to old projector

[veselinv]

Please, help me to connect stb TVIP 605 with an old projector Benq, which has AV input, S-video input, and two VGA computer inputs. I tried HDMI to VGA cable, composite video, cable which is coming with box to AV cable, but no success. Mag 254 worked on boath outputs. Thanks in advance.
