CharlesGrey: When you say "composite cable", do you mean the one with the red, yellow and white plugs? Because that one has the worst picture quality and should be a last resort for an HD device. ( Or any electronics device. )
Should have 5 plugs, 2 for sound and 3 separate ones for the video signal.
Problem is, not all screens have the proper ports for that type of cable, so worst case just get a decent Scart cable for your PS3. No HD resolutions, but at least the overall quality should be OK. Or just try that other solution once more... Maybe there's some other settings you can try?
Sorry, I mixed component and composite. I meant to say component :) I didn't know composite had the worst quality. I used that on my Xbox 360 for years :P (and still use it for my first-generation Xbox). It does not look like my TV has support for component-cables though. I'll look for a Scart-cable. I could also try some different resolution-settings first.
CMOT70: Sorry, I sold my PS3 and am just going on memory here. But the PS3 had some odd issues at times. One is that it does not always upscale to 1080- you must set that in options through the menus. Otherwise a game can and will output it's own resolution which in the case of the low aspect ratio of Beyond...may be a resolution your TV does not like. The game ran for me, but I was using a monitor and I had to to play with the settings on my monitor for ages to get the game to play without stretching vertically for example. So make sure you have upscaling enabled then you know you're outputting 1080. Any modern display device will display a 1080 input for sure, but not necessarily an oddball game resolution.
It would be nice to know beyond doubt that the game really is running correctly first. If you have an optical audio cable then you can determine this by going to the PS3 audio menu and forcing audio via 44khz PCM (Pulse Code Modulated) digital output. That will make the audio go out the optical port instead of (or as well as possibly) the HDMI cable. Then plug the optical cable into your amplifier, start the game and see if you get sound during the game starting. If so then the game is definitely working and you know you just have to solve some display/device incompatibility. Though...now that I think about it, maybe Euro PS3's don't have optical audio outputs...with that SCART port taking up so much space and all.
I don't know if I have upscaling enabled, I'll check it out. By the way, I see the TV-overlay appearing in the corner of the screen when I start the game, saying that the current image is 720p. When I'm in the PS3-menus, it says 1080p, so I guess the TV just adapts to whatever resolution the current image is. If BeyondTS is running at 720p, it shouldn't be an issue. It's still 16:9. I don't know if the game actually runs at 720p though. It could be a case of the TV failing to change the resolution farther though, as you're saying that the game runs at a funky aspect ratio. I could try to change the output-resolution of the console to match the aspect ratio of the game. Do you know what aspect ratio/resolution I should go for?
I don't have an optical audio cable, and no amplifier, and I don't think this PS3 has the port for this :P It's a very good idea though.
