The "fix" included new tuner improvements to better handle the FiOS signal. That eliminated massive RS Uncorrected errors that caused pixelization. If you aren't seeing RS Uncorrected errors on your DVR Diagnostics screen, then you you should see the signal exactly as delivered. If you're still seeing larger numbers of RS Uncorrected errors (i.e. tens of thousands), then those could cause dropped frames. Stutter can also be an early indicator of internal or external drive failure; stutter is common on My DVR Expanders that are starting to fail. As mentioned above, various display settings on some popular Samsung, Sony, and Toshiba 120-240MHz LCDs will also cause stutter with certain signals regardless of your box and provider, which you can read more about on the AVS Forum.
