Review update: Series links are working well (or maybe I'm just lucky). I have 6 series links and so far, its recorded everything I've asked it to. Sometimes I think its screwed up, before I realise that series link only records
new episodes
Sometimes when re-ordering the priority list of series links it appears to lock up - its just says 'loading data, please wait' (or something like that), but pressing TV fixes it and it DOES actually save your priority settings.
I forgot to mention how quiet this thing is - I was worried when I read past reviews, but my TV Drive is around 5" away and its as quiet as a mouse. I wouldn't advise putting one in a closed cabinet - keep it well ventilated.
All recordings I've made since
The Unit have been fine - no drop outs of sound.
IMO, the 'dropped frames' bug only appears after watching recorded content which was recorded when 2 tuners were in use. Other stuff I've recorded was only using the 1 tuner (AFAIK), and watching live content after watching those recordings has been fine, no dropped frames.
The only annoying thing really is the 'slow response to remote control bug' - as I type this, my TV Drive has been ignoring me for about 5 minutes now (maybe it knows I'm typing about it.

.....bugger it - its locked up - time for a reset)
