FYI - In case folks weren't aware, an audio quality problem with the Left stereo channel has been uncovered in regards to the Zenith, Insignia, and DigitalStream boxes that utilize the LG chipset. You can read through the issue as it begins to unfold here, starting at post #493. It seems LG is aware of the issue, but hasn't openly admitted to a problem.

For folks who are interested in the Zenith/Insignia, your best bet might be to wait for the Zenith DTT901 or Insignia NS-DXA1-APT which were scheduled to be released on April 14th and should hopefully start showing up somewhere in the next 4-6 weeks. The newer models will include an RF pass-through that the previous Zenith/Insignia models don't have.
