Blure ray remotes - Samsung BD-P1200 Blu-Ray Disc Player

you can just buy an Android-based phone, and download a piece of free remote control apps as well as installing it on your phones.

You should download the latest firmware from the website and update your player. If that does not work, the blu-ray lens eye is bad. There are 2 lasers that read discs, one red and one blue. The red reads normal dvd. The blu reads blu-ray.

your monitor maybe having hardware problems.

how can i install on my pc? but the camera is not responsing on my pc

If it's been like that since Day 1, I'd guess either an improperly assembled lens, or a misaligned CCD in the body. Hopefully it's a warranty fix. If it has recently started, it may be due to impact to lens or body. Fingers crossed for the warranty situation.

look and see if there is a way to adjust the focus on the camera. On some logitech cameras that center lens piece can rotate, allowing you to change the focus.
