Hi,

I was wondering if anybody could help me. I have got a VGear MobiDTV USB 
DVB device. It is detected and installed fine with the dvb-usb-dtt200u 
driver and the zl10353 driver. It also loads the 
"dvb-usb-wt220u-zl0353-01" firmware correctly.

The problem comes to when I try to tune. I have changed the frequency in 
the Crystal Palace tuning file to 506000000 as I have read so far. This 
allows me to tune to 18 channels, far from the hundred odd the device 
picks up in windows. The scan program just keeps going through all the 
frequency's just saying tuning failed. Here is a list of the channels it 
can detect.

I can watch the listed channels fine in Xine, actually I have no sound, 
but I am guessing that is a different issue. I have also used a 
channel.conf from a working PCI tuner to see if it was just a scanning 
issue. But this too did not let me watch the other channels.

So if anybody knows why this might be happening or how to fix it please 
let me know.
