Google Youtube suggestions for player - settings for quality and annotations in profile

To google support
1. in full screen goes to HD even if i made it go to 480 or 360p in earlier videos. can you add a setting in profile for your player not to do this? Why? Live in India, pay INR 1300/- per month to a "fibre" optic broad band provider (ACT) but still get slow connections, except for their sponsored speedtest site! duh. If your player does not go to HD i can watch without pauces and bad breaks.

2. similarly with annotations - a setting in profile to turn off by default

Note this was shared via the feedback tab too but re sharing so others who agree can send to them as well

Java: rename file : file_0001.dat, file_0002 to file_0004, file_0008.dat

Issue: bunch of files name file_0001.dat, file_0002.dat......file_1000.dat.
 I want to change the file names such as the number after file_ will be a
 multiple of 4 in comparison to previous file name. So i want to change 

file_0001.dat to file_0004.dat
file_0002.dat to file_0008.dat 

Start from the highest and go to lowest. As 
if u go from lowest - there will be conflicts. example u cant rename 001
 to 004 if there is a 004 from before ...what if it at first you have 
file_0001.dat, file_0001.dat, ... file_0004.dat.

Utility script to make a few files, test helper
touch file_0001.dat touch file_0002.dat touch file_0004.dat touch file_0005.dat touch file_0007.dat This version just start the program in the same dir as the files, after compiling and changing the classpath
