Samsung P181 subtitles and Firmware problem

[skech]

My name is Marjan and I purchased DVD player P181 because it’s slim. But now I have problem with the subtitles. They are very small and I almost read them. There isn’t an option to resize them. So I tried to install the new firmware from the official site but when I insert the disk nothing happens the firmware isn’t recognized. I search the web and found lot of people with same problem so I decided to ask some help from you. So please help me with the subtitles and the firmware
Thank you

I've never seen a player with a resizable subtitle font. So it doesn't surprise me that you can't adjust them.

As for your firmware issue, you likely didn't properly burn the disc. The manufacturer typically supplies instructions with the firmware (either on their site or in the zip file) which outlines step by step how to burn the file. Their are often specific options to be enabled/disabled and it must be burned in a specific format. At least in my experience, you can't simply download and burn it to disc using default options like you would any other data files.
