As far as I know, ATSC EPG doesn't account for time zones, usually the time is based on GMT +0. (I may be wrong on this, but most of the online ones are that way. I'd have to read up on the specs for it to be certain.)
The guide in the units *IS* affected by DST changes in the time zone even *IF* you tell it you don't observe it (like I am right now).
My unit is: Manual time set, manual recording (the guide is a big waste of space). If the unit says the time is 8pm, the guide shows 9pm (and the current show on at 8pm).
On Sunday (March 9), I manually moved the unit's clock forward (DST observation setting is still off). So people in a time zone that may/may not use DST, will find the guide does, completely ignoring their DST observation setting.
From February 9 to March 9, the guide was 1 hour ahead the unit's clock (because it jumped forward Feb 9 along with my "brain dead" Samsung 6k Series HD LED TV, Samsung says there isn't a fix either, I said, "Thanks for using wrong DST values in a 2 year old TV, not like you didn't have a few years to get it right."). Feb 9 to March 9, I had to have DST observation off (what ePVision said to do in an email), in doing so, no guide programming would work at all (it showed as "to be recorded" even in the EPG listing for the channel), no recordings worked, all ignored. Now, since March 9, the guide is behind 1 hour with the manual time set ahead 1 hour. The guide is worthless until I allow it to properly set the time and DST, but that will only be good until October (when I know it'll swap back, as the 1st unit version did for a friend). Now without knowing 100% if the EPG does include time zone information (over the air one, not something else), I can't tell if they've trashed their thinking on how to properly do the guide. I *do* know my ATSC tuner on this PC has absolutely no issues with time zone changes with it's OTA EPG, using the proper time zone & DST dates. My thought is, they botched the entire EPG and DST dates.
Current recommendation for anyone in EST with this unit: No guide programming, turn off all of the auto-clock updates, DST observation set to OFF, manually set the time and manually set recordings. They work 100% this way, any other way, you could be in for a headache if the station you're watching might provide their local time to the unit, which could throw it out of the time zone you're in.
Hmm, I think a good slogan for this would be, "If all else fails, go manual!"
I snapped a picture of my TV showing Mr Ed at 3:30PM (2.3), the "Info" shows Mr. Ed at 2:30PM...
Well, simply put, in Ontario Canada, unless you want to pay the 2 major media companies (Rogers or Bell, there *ARE* no others, they own the rest of the "competition"), you're stuck with OTA (wouldn't say that is a bad thing, been OTA since it became a reality in B&W days). Now, recording OTA requires one of two things, a PC (~600-700 for a decent 4 tuner setup) or a recorder capable of doing so. Well, our Panasonic DVD-RAM PVRs (we had 3) are dying (we've lost 2 in the past year to U99 errors [means it's a brick]) and at $350 to fix it, this was cheaper.
I was *hoping* to not buy the unit but build a HTPC to actually fit into the cabinet under the TV and function without headaches, but, sadly, at double the cost of the unit for 3 tuners (since we had 3 PVRs), how fast our second PVR died (mid-season), I didn't have the time to buy the necessary components (US suppliers only for HTPC products), I decided to buy this unit, as a means of not "breaking the bank on a PC that will sit and do nothing half the time". Arguably, the HTPC alternatives, also have people griping about the interfaces, so you could say it's a "crap shoot" (literally).
As for recording manually, I actually have an Android phone and tablet. A free app called "i.TV" will give me a scrollable EPG for OTA and I can schedule shows from that, plus it usually goes 2 weeks ahead. So programming without the guide is as easy as it was with a VCR (remember those old tape munchers?) and a paper TV Guide book.
But, the recorder doesn't crash nearly as bad as the DVD-RAM PVRs we had, it's on an APC (like I wouldn't, it's basically a small PC in a box). A suggestion over and above the power switch on the back (since that may be a bit harder to do), a hidden flip-open compartment with a USB port and a pen sized hard-reset button (our DVD-RAM PVRs have this setup and it works well). One other recommendation, use a watchdog thread to watch the video on all active tuners, on the original 1st version and mine (the second), I've seen the tuners *partially* crash (audio works, video stuck on 1 frame). Power cycling seemed to work for the first version, but since there is no power button, the power chord was yanked to do the same thing (hence that nice reset button up front or at least a watchdog thread to monitor the tuner's video sync).
While I'm at it, the "Medial Player" window says "Record" (umm, why?) and the lovely "dead" clock in the upper right corner (if you're not going to update it, just remove it).
