I bought the Pinnacle nanostick 73e about two years ago, but was unable to use it on my Toshiba Satellite M60 laptop, which has a 2GHz intel type M processor. The box said the software would run on my system. Then I found the fine print - HD720p as used by television in NZ would not run. Indeed, TV1 froze after a couple of frames. I uninstalled the software and put the package away.
Last October I bought the Toshiba Satellite L650D laptop which runs an AMD Trurion core duo processor, roughly equivalent to an intel core duo i3. Since that laptop renders HD720p video at less than 100% CPU duty cycle, I gave the nanostick another try. Windows 7 did not like the installation from the enclosed disk. I found the latest Pinnacle installation - TV Center V6.4. This would install and run, but with stuttering audio, and after a few channel changes, the program would freeze.
I un-installed TV Center V6.4 completely and restarted the computer, then plugged in the nanostick. Windows 7 has the drivers for it and installed them! Was TV Center V6.4 ignoring these drivers and duplicating them?
I decided to check out the Windows Media Center that came with the Windows 7 installation. With the nanostick 73e plugged in, the 'live tv' part of 'Windows Media center' indeed found our Freeview channels and loaded them, and it plays them without stuttering. Changing channels can be done by entering the numeric keys, without freezing the program. I have not yet tried recording TV programs.
The moral of the story?
You do need a Windows 7 installation on a core duo chip set (intel or AMD), i3 or equivalent, as minimum. This will recognise the nanostick when plugged in.
Do not attempt to use the Pinnacle TV center 6.4. It does not appear to check for pre-existing drivers, and Windows 7 does not check for any TV Center drivers either.
