    hi. Pinnacle has a few HDTV tuner devices for pc's. At Best Buy for a black friday sale, they have one that is USB, but here's my question. The minimum requirements for it to work is having a Pentium 4, 2.80ghz CPU (or an Athlon64 CPU), and 512mb of ram.

    Does anyone know if these are a definite requirement? Has anyone ever used such a device on a 1.80ghz machine that had 512mb and it worked? For $59.99, it looked pretty bitchin! I will probably buy a new, modern laptop next year that will allow the HDTV tuner to work, IF it would never work with a 1.80ghz machine, which i currently have.

    ATSC is already compressed as MPeg2/AC3. An HD tuner just feeds the decoded MPeg-TS/PS stream to the drive system. The CPU spec is needed to preview or play the file. The display card can assist with MPeg decode and rescale. Your system is probably not up to the task. Try to obtain some ATSC HD streams to test your system.

    Make sure the tuner stick supports QAM decode if you expect to use it with a cable system.
