hi

Could you help me changing the resolution quality for this live video:

to download it i found this link /:

but they are constantly changing the token but i found in the source code that there are possibilities for resolutions:

<smil:switch>
<smil:video src="ajswebch350_1_2400@s13848" system-bitrate="2400000"/>
<smil:video src="ajswebch350_1_1500@s13848" system-bitrate="1500000"/>
<smil:video src="ajswebch350_1_1000@s13848" system-bitrate="1000000"/>
<smil:video src="ajswebch350_1_500@s13848" system-bitrate="500000"/>

and the source code link is :

so how could I make it working for this reolution :
src="ajswebch350_1_1500@s13848" system-bitrate="1500000"

it isn't easy i hope you could help me.
thanks in advance
