Only shows on film go to HD. Matlock was shot on film but edited (and aired) using videotape thus it would not be a candidate for HD. The same was true for Diagnosis Murder. I'd guess the same is true for JAKE/FATMAN but admit I haven't seen those discs. The only way Matlock could ever be in HD is if CBS/P went back to the original film negatives and re-edited each and every episode and redid all the graphics, etc. Not gonna happen in all liklihood. I netflixed Cannon disc 1 and it definitely was not sourced from an HD master (if it was, it was one of the worst looking transfers to HD I'd ever seen) so my speculation is that the elements existed only on videotape or CBS just cheaped out on this one series. Gary - I hope for your sake that RAWHIDE is simply out of date on the CBS website. MASON S3V1 was already released before this latest update. Question for Gary or anyone else who frequents the CBS site: has anyone ever gotten the "LATEST REVISIONS AND ADDITIONS" link on the main page to work? I never have; and it would be much easier to see the changes listed than go hunting and pecking individual series.
