2) Karaoke with languages other than English show rubbish
It is required to set text encoding:
Go to menu Tools, Database manager.
Select folders which contain midi, mp3 karaoke files.
Click "Show more options...".
Select correct text encoding for your language.
Make sure "Clear cache before scan" is checked.
Click "Scan this folder" to scan folders again.
3) Slow, video and audio are not synchronized
Computer is just weak. (fullHD, 60fps).
Try set Hardware Decode: in Settings, Video Decoder select Hardware decoder as Dxva2Native. Some old video card Ati (AMD) is buggy when decode video 60fps. In this case don't turn on Hardware Decoding.
Some laptop can switch between integrated video card Intel and dedicated vide card. Check and set which video card to be used in LetmKara.
4) Youtube doesn't work
Check internet connection.
Try youtube in web browser and restart LetmKara.
Some videos don't allow to be played as embedded video outside youtube website.
5) Error "Oops. App just crashed ..."?
Program crash. Click OK, an error message will appear. Please copy that message and send me so I can check.
In case there isn't any message, please go to the directory where you extracted program, zip the log folder and file crashdump.txt, and send me so I can check.
6) Remote control client cannot connect to server PC
Check firewall on your PC
Check if PC and phone are on same LAN
7) Remote control on iOS and Windows Phone?
There won't be any any time soon. Because Apple doesn't encourage indie programmer like me. It is required to pay 99$/year to maintain a developer account and a Mac computer to develop mobile app. While with Google, only one time payment $25 is required. Windows Phone is kind of dead so also no.
