When I try to play my video files in SMPlayer it works fine but as soon as I switch to fullscreen mode(16:9) following thing happens:

1) Video starts lagging.

2) Audio and video goes out of sync.

3) CPU usage rises to ~50%.

4) SMPlayer starts to hang.

My current SMPlayer configuration:

1)Video Output Driver = x11(slow)

2)Audio Output Driver = alsa(0.0-HDA Intel)

3)Cache = 8192 KB

4)Threads for decoding(MPEG-1/2 and H.264 only = 2

Things I tried solve this problem:

1) Tried changing video o/p driver to xv,gl.

2) Tried changing audio o/p driver to pulse.

3) Tried increasing cache size and also tried using nocache.

Everything works fine on windows but I don't want to switch to windows just to play video files.

My system config:

Acer Aspire One D270

Atom N2600(Cedar Trail) 1.6GHz

2GB Memory

Intel GMA 3600 graphics.

Ubuntu 12.04

Kernel Release: 3.2.0-23-generic-pae

Rest all things are working fine I have no resolution issue, bluetooth, wireless also working fine.

Just ask me to submit any other log file I will be happy to post.
