A bit gaming and sheeps don't get airporn like in carmageddon.

Peazip compression fetures, crash and bad multithreading, computer freezes all the time when spliting large files.
Peazip displays double icons on left bar.

Microphone not working with Realtek ALC889A int audio.

Scanning problems, bad colors and no dpi choice, closed windows can not be opened anymore.
Right mouse click and select default program to open the file, on 800Mb 3*16bit TIFF image will crash Ubuntu.

Web browsin works on satisfactory level.

DVD movies play nice and smooth after process in below (not shown in short version because of copyrights).
sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh

No good hardware acceleration for x264 movies, 1080p cpu in Ubuntu 88% but in Vista 11%

OpenShot Video Editor has no custom video resolution option in file save.

Avidemux window won't fit inside monitor resolution and can't scale it down.

Gimp 2.6 after first start and before reboot won't fit inside screen resolution. Can't grab it's tool windows.
Gimp has no 3*16bit support.

Blender has no encode video to huffyuv option.

FFMPEG has no Lagarith Lossless encoding capability. But can make huffyuv.
FFMPEG can't encode to x264 with 4:4:4 chroma subsampling and i444 colorspace.

x11grab -follow_mouse option not working.
Here is an example below what is not working:
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1280x720 -i :0.0 -follow_mouse 180 -acodec pcm_s16le -vcodec huffyuv -sameq RAW_Lossless_huffyuv_Screencast.avi

I screencasted with line below (cose my mic didn't work):
ffmpeg -f x11grab -r 30 -s 1680x1050 -i :0.0 -vcodec huffyuv -sameq RAW_Lossless_huffyuv_Screencast.avi

I added black bars because my screen res aspect ratio doesn't match to 1920/1080=1,777 but i have 1,6.
And there is no point scaling it up all blured just for aditional 30p from 1050 to 1080.

I encoded video with VirtualDub x264vfw:
Preset: Veryslow
Tuning: None
Profile: High
Level: 5.1
Fast Decode
Zero Latency
2 pass 4096 kbit/s
--keyint 300 --min-keyint 1
