Probably. Maybe. I tried to get one several times in past years, in order to confirm it, but it never get low enough to meet my gear gambling limit. For whatever reason, costs were always higher on these (at least when I looked, and it's been several years now).
In related new:
I did recently acquire another ES25, since msgohan/Brad kept insisting it was comparable to the ES15. My first test several years back showed performance was pitiful. So we shall see this time around. There's always potential that it was infamous mid-production changes, and is another variable item.
At least everybody agrees that the ES20 is crap.
I was able to confirm the EH75V is at least partially viable, need to still test it with nth gen. But it's a really heavy HDD unit (I mean REALLY heavy, too!) and has faults that make it a problem unit unrelated to the passthrough. And if you buy this thing from eBay
, knowing how horribly typical sellers piss-poor pack gear, it won't even arrive to you in piece. The weight of this thing makes it unattractive. But if you can find one in person, and don't have nth gen (performance not yet confirmed), for cheap, then probably worth it, if you want an anti-tearing and minimalist TBC(ish). Noting that it should still be paired with a weak frame TBC like the DVK, don't entirely rely on the line TBC with non-TBC frame sync (same goes for any of the DVD recorders).
Note that NR is always on. "off" is essentially low, while "on" is aggressively high. It's never untouched, always some % of NR going on. I would assume it's meant to aid MPEG encoding to DVD.
