I've just started to test HW-150 firmware version 5.5.1, and it looks like a bug that's been around for five years has finally been fixed. I call it the "midnight scheduling bug" or sometimes the "second midnight bug" (because there was another bug related to midnight that was fixed long ago).
Here's how it works: Schedule a weekly recording for some time today. Now try to schedule another weekly recording that starts today but ends tomorrow. Most of these boxes will reject the second weekly recording, saying "This schedule is conflict [sic] with Eventnn," even though the two events don't overlap at all. (If you schedule the same two recordings in reverse order, i.e., schedule the one that ends tomorrow first, it works fine.)
But V5.5.1 works correctly, letting you schedule both events in either order. FINALLY! Folks have literally been complaining about this bug for years.
Unfortunately, one serious bug, the "channel rescan bug," remains. This is a problem because it makes it impossible to record certain channels (e.g., Ion) reliably. Those channels may (or may not - it's seemingly random, except the longer it's been since you tuned in last, the more likely it is to happen) rescan the next time you tune to them, losing any customized names, favorites, upcoming recordings
, or skipped channels, and bringing back any deleted channels, on the same signal.
So if reliable recordings are critical, I still recommend the iVIEW firmware (version 20160923V5.0, along with an iVIEW remote, of course) I mentioned several posts ago.
Other observations: CCs during playback still work. (I check that first, since the developers have broken it before. For example, with the iVIEW firmware mentioned above, turning CCs on during playback may work, or may lock up the box!) Boot-up time (on my iView 3200 since I don't have a compatible HW-150 to test with) was a respectable 15 seconds from pressing the "On" button to video appearing.
One (very minor) difference between HomeWorx and iVIEW firmware I didn't notice before: iVIEW eliminated the largely useless "Power On/Off" schedule when they added the 12-hour time option. HomeWorx kept it; instead, they eliminated the almost-as-useless manual time zone setting, which lets you select your time zone relative to GMT, rather than by name (Pacific, Mountain, Central, etc.)
I'll do more testing later, but for now I'd say V5.5.1 isn't quite
there yet, but it's getting pretty close! Now, if only we could combine the HomeWorx and iVIEW fixes, we'd be just about perfect.
