The Plextor ConvertX TV402U external Tv Tuner is great product. I personally purchased one a few weeks ago and have been very happy with it. It retails for $199.99USD on the Plextor website, but TigerDirect retails it for $158.99CDN and NewEgg retails it for $178.99USD.
Essentially what a tv tuner card allows you to do, is to connect your current cable to your computer so that you can watch and record programs directly onto your hard-drive. However, previous versions of the ConvertX did not contain the PVR utility that the TV402U model comes with.
It is a breeze to set up. All you really need to do is install the drivers for the product, and install the software and you’re good to go. A quick channel scan (which takes about 15 seconds for 100 channels) and you’re ready to go. The only problem is that once it’s all done with, you’ll have to manually go in and set up your favourite channels. However, this isn’t too much of an inconvienience as the Plextor Setup menu has an option to rename the channels to whatever you want, as well as save them to a favourites list. The bonus of the favourites list is that you can jump to any of those channels at any time. Otherwise, you’ll have to load the setup program again, and select a channel to switch to from there.
The TV402U allows you to record programs in mpeg-1, mpeg-2, mpeg-4 and divX format, meaning that you get great quality out of this little device. As well it offers many different bitrates depending on the quality of recording that you are after.
The TV402U also comes with provisions to hook up your VCR or Camera over RCA and record it to your comptuer. While you won’t get digital quality recordings (because everything is analog) your quality is still quite good.
One thing to be wary off when you are looking into purchasing any tv tuner card for your laptop, is that as of February 2009, analog cable signals will no longer be broadcasted in canada. What this means, is that you will need an extra digital cable box from your provider. However, since the only inputs that your tv tuner will have are analog, your signal quality will drop quite a bit and you will no longer be getting your digital signal.
