guys,
abhi to mein ne videos mein sirf yehi show kia hai k how i control the media player from mobile...
i have got another option... mere laptop ki screen, complete ya iss ka portion mere mobile ki screen pe aa jata hai through the wifi connection, thus i dont even have to press even a single key (on laptop's keyboard) or use its touch pad to control the cursor 
@yousaf: yaar, its simple, i have given u the key combination above. just try Ctrl+Alt+(any arrow key)
@imadee: laptop car charger bhi achi option hai, but uss pe bhi to 1500 to lagne hee hein, plus universal hona implies k it wont be an original for sure, ya to khud bhi faarigh ho sakta hai, aur laptop ki battery ki life to zarur kam karey ga
