I know this will hurt, but what did your local cable office tech support say? On the other hand, Fox is causing channel games with FS1 and Speed. This advice assumes Metrocast knows what clear QAM means. If not, then we can hope it doesn't repeat. Good luck.
I understand. Sometimes these stories have happy endings. Sometimes not so much. Since you sound like you know what you are doing, can you get a second opinion from your TV? My cable signal runs from 94 to 96 on the 515H. My other stuff also shows SNR which is about 37db.
My feeling is that if you can record something bad you are receiving something bad and it's not a fault of the DVDR. This is not absolute, but pretty close. And I could just say "Google QAM" but here is some nice info with pictures: http://www.engadget.com/topics/hd/2009/05/08/hd-101-what-is-atsc-psip-qam-and-8-vsb/ and to keep it simple, people mix QAM, ATSC, NTSC all the time even though they are mixing apples and oranges.
QAM is the way digital cable sends data. OTA uses 8VSB but people like to call it ATSC. I think maybe it's because VSB sounds like an STD.
That's interesting for the possibility that the 53x Series might have something different in this regard compared to the older units.
Only way to know for sure is to record something with visible "markers" and compare set points with end points after HSD. I used CNBC during stock market times where they run dual banners at bottom with triangular icons indicating up or down movement, as I reported here... tedious but it gives a definite indication of mark locations before and after HSD.
It would be nice to know if something has changed in the 53x units.
I wouldn't lose sleep on this. I've been doing back to back recordings for years and never missed anything. I blame things like this on cosmic rays.
You're not alone... see this post.
If Dividing works for you, keep doing it.
Can't create a 2nd copy of a HDD title on the HDD except by burning it to a disc and copying it back.
DVDs with multiple titles play back all titles sequentially, with a slight pause between titles.
Being in such a great area for free antenna TV, I'd certainly go to OTA now. I'd love to be able to do that since we get 100% of our recordings here from the networks, but we're 50 miles between larger cities in opposite directions.
If you have a HDTV with analog and digital tuners, you might try connecting the incoming cable directly to it and scanning for channels to confirm that it, also, can't pick up any channels before you declare yourself totally enslaved to the Comcrap Monster!
They also might be "practicing" for the enslavement action and, since lying is in cableco genes, you might not have to get an antenna since you may still be able to tune the local channels and networks with plain cable... you just never know for sure until you know for sure! Wait a bit before getting that antenna, or use an indoor antenna for now?
This sounds like some other problem, like the govt coupon box, rabbit ears AND bowtie antennas... didn't know those were in the system. I assume you need the box because you have an old TV that doesn't have a digital tuner? If so, and it still picks up your channels, the Mag should do the same.
Since the Mag can replace the box (except for watching and recording diff. channels if your TV doesn't have a dig. tuner), I'd test the Mag alone... remove the box and one of the antennas and connect the antenna that fed the box directly to the Mag.
Do one or more Auto Channel Preset > Antenna in the Mag and see what happens. This way, we're isolating the problem to the Mag and can go from there.
Welcome to the forum... I'm glad you decided to join us!
You don't need a 3-way splitter, which degrades the signal more than a 2-way... in fact, one output of a 3-way is usually twice the signal loss of a balanced 2-way.
Use a balanced 2-way splitter with one output directly to Mag 1st, then out from Mag to TV. The amplified splitter inside the Mag will pass the raw incoming signal thru to the TV while feeding its tuner.
You must have missed the part where I said "The amplified splitter inside the Mag will pass the raw incoming signal thru to the TV while feeding its tuner." But that's now a moot point.
At this point, you could reload the tuner FW (Ver02C)... maybe it's been corrupted somehow. Info on that is here. Since you have a 513, you'll need only Ver02C.dtv and BE 727V FW... 727V will make your 513 operate like a 515.
