I don't think so. A few points in support of my argument:

1. Errors are detected and logged as uncorrectable packet errors
   and/or transport stream continuity errors. I don't see long
   streams of these in my logs, though I will double-check.
   
   These usually translate into big collections of ffmpeg errors,
   which I am getting on SBS HD for example but not the others.

2. HDTV and SDTV are on the same frequency. The error rate should
   therefore be roughly the same. My SDTV might error every 20 minutes
   or so but not more often than that.

I live in the eastern suburbs with good line of sight to the Mt
Dandendong transmitters. I don't have superb coax but it isn't an issue
with the SDTV stations.

In any case I'm moving house very soon so I can test your theory then
(brand new antenna plus quad shield cable at the new location).

Might be an audio driver issue. I'll try OSS emulation too.
