thanks for that happen he'll see the post i have the link to that site , its not obvious which bda driver to download, since posting sometime ago expect the software and driver has changed since we last talked about it model is vp30540
If you mean the Twinhan DVB-ter Digital + Analogue (D+A) PCI card, the model number is 3054.
The software is the second download down (All Models except 7021 etc) and the BDA drivers are the third download down (listed 3054).
I find the best way to do it is to install the software first and, once that has been completed and the system rebooted, to reinstall the 22.214.171.124 BDA drivers again from the folder to which you have downloaded them.
Once these have been reinstalled, reboot again. Then you will be able to scan for the TV and radio channels (Control Panel>click on green area on extreme left>click on second button from right on top line>DVN-Terrestial Setup>>Antenna>only tick boxes from around 24 onwards>Scan).
It's likely that some of the channels will be duplicated. After clicking on the Configuration button, delete each duplicated channel keeping the lowest channel version each time for both TV and radio stations.
Depends on your signal strength and quality i.e. how far you are from the transmitter.
I'm about 15 miles from Winter Hill (I can see it, in fact, from the end of the road), so get all the available channels on both the Twinhan software and the final version of ShowShifter.
Showshifter provides slightly superior picture quality but, unlike the Twinhan software, you can't have it on screen in a smaller window whilst browsing; ShowShifter, of course, uses the Twinhan BDA drivers.
