Hmmm... interesting finds for this model. Apparently built buy ECS for Walmart distribution under the name of Balance.
There is no Balance website and no information from ECS. But from what I have gathered this evening, from searching online, it should be the same as the ECS line of laptops from the same time period.

Scroll down to model 332 and try the TV driver listed on the bottom of the page. Most of these models from ECS share the same LifeView TV Tuner driver.
I couldn't find any relevant specific information for Balance CN1401. Other than it being an ECS built laptop for Walmart Balance branding. So theoretically, and ECS driver should work. If that one from the 332 doesnt work, then check some of the other models listed.
Is this going to be for Windows or a Linux based operating system?
