I'm puzzled - where did I blame the HDD? If anything, I blamed the codec, which is software. But that's only speculation - I really have no idea what causes certain recordings to be unviewable because of skipping.
Because your post only made reference to the HDD & the recording. If it was all or any of what was said, why wouldn't all other recordings exhibit the same? I have read more than once about certain stations causing problems to other devices, this may be one.
But, trying it on a PC is a good suggestion.
BTW; I don't use mine at all, it just sits above my desk as a spare tuner w/ a HDD enclosed, which replaced a 205 tuner. You know the one that has the rotary heads that are unbalanced (that still works fine).
They did get the tuner correct, in fact that gets 5 stars (and I almost never give anything 5 stars).
