there are 3 seperate parts to using these most of these DVB-T devices.
theres the required BDA driver set OC, then that cold boots a DVB software firmware into the USB2 device, only then can the DVB app player/tuner can start using it.
in the case of the the two mentioned they should both be using idVendor
0x14aa AVerMedia (again) or C&E drivers in linuxTV
for the
27442 it should be idProduct 0x0620 and
25452 should probably be reported as using idProduct 0x022a when the firmware is loaded...
then its just a case of using any generic BDA TV tuner app such as

basicly if your drivers seem to be installed adn your getting crashes from your chosen BDA driver app try any other in this list or other BDA TV app you find.... the apps are usually the worst part of this puzzle as the drivers and asspecially the software firmwares are virtually the same across all OS platforms.
you might also try using a liveCD linuxTV CD of your choice and boot directly to that instead to test and play with your DVB-T and tuning... once you have a good external arial plugged in to each of your DVB-T devices...
