Here is how to get youtube flash movies to work with opera 9.50 beta 2 build 1933 and flash 9.0.124.0
1. open terminal/console and copy paste this line
find / -name libflashplayer.so 2> /dev/null
2. the path to libflashplayer.so file will follow (something similar to this should appear)
/opt/netscape/plugins/libflashplayer.so
/usr/lib/nsbrowser/plugins/libflashplayer.so
3. go to console login as root and navigate to the folder containing libflashplayer.so
4. copy libflashplayer.so file to /usr/lib/opera/plugins/
5. open opera go to tools ----> preferences ----> advanced ----> click on plugin options ----> click change path
6. the only tick that should stay is the tick next to /usr/lib/opera/plugins/ box all other boxes should remain empty. that way opera will only look for plugins in that specific directory
7. confirm the changes you have made
8. test the plugin on
youtubep.s. report back if this suggested metod works for you
