Windows’ default

“MPEG Audio Decoder”

(as part of quartz.dll) can often fail to properly decode

MPEG1 files’ audio: resulting in Windows’ MediaPlayer giving corrupted sound on playing MPEG1 files –
this can be fixed by making MediaPlayer to use a different MPEG Audio Codec Filter, such as the free
“

MADFilter.ax

” (

http://sourceforge.net/projects/maddxshow/

) for Windows XP and Vista, or the Microsoft

MPEG-1/DD Audio Decoder Filter “

msmpeg2adec.dll

” for Windows Vista/7, etc.: after registering these

filters using regsvr32.exe, set their Merit value (using free tools such as RadLight Filter Manager or GSpot
etc.) higher than the Merit value 0x03680001 of the default MPEG Audio Decoder, then reboot Windows.

(5)

To use third-party DirectShow-enabled software such as VideoLan(

http://ww.videolan.org

) etc. to

access the uncompressed analogue video on PC, click the “

Disable M2B Device

” button on the

Device

Setup

Window to disable the DirectShow graph built by

USBOSDM2

application

software

.

Note in this

application software only one

M2B

device can be disabled at a time ---

USBOSDM2 SDK

will be needed

to disable multiple

M2B

devices and use DirectShow filters: details can be found at the “

Using DirectShow

Filters with the SDK

” section of the

USBOSDM2 SDK User Manual
