Chapter 11 limHD200i FAQ
11.1 Choppy while playing with USB CD/DVD drive
Probably caused by the following reasons:
¾
Videos have too high Bit rate. USB CD/DVD drive generally supports an average bit rate
of about 20Mbps (peak value is certainly higher than this value). We suggest you to copy
the videos with high bit rate to the internal HDD to play.
¾
The video data has big BER which also affects the smoothness. A big BER is usually
caused by disc distortion or dirtiness. It is also caused by poor error correcting capability of
the USB CD/DVD drive, including the original data error. We suggest you not use discs
with problems; neither can you use the USB CD/DVD drive with poor error correcting
capability to play the movies.
¾
The USB interface cannot work under USB2.0. The reason is that the USB interface chip
used by USB-IDE ADAPTER does not accord with the USB2.0 Standard. Or using a USB
connection cable ill of rapid transmission capability. We suggest you to use the USB
CD/DVD drive (or USB/IDE ADAPTER) allowed by USB2.0 standard and use the accessory
USB connection cable.

11.2
Cannot find the USB devices newly connected
When you just connect the USB devices like USB Mobile HDD, USB CD/DVD drive or need to
change the disc, it displays empty and you can not visit the USB devices or newly changed disc.
Such problems are probably caused by the following reasons:
¾
You have not refreshed your USB devices. At this time you need to go back to the main
menu and refresh the USB devices (select
USB icon
on main menu.). For more details
please refer to
3.3 Refresh when changing the newly connected USB devices.
¾
USB devices are not connected properly. Please check carefully whether there are some
problems with the power supply (as some USB devices need outer power supply). To check
whether it is in normal operation, the direct way is to connect the USB device to PC; to check
if there are disc damages/problems, the direct way is to put the disc in the CD/DVD ROM of
PC to see if it can work.
¾
USB connection cable problems. We suggest you use the accessory USB cable or other
USB2.0 Standard cables.
