It isn't ambiguous compared to the Dish Hopper which is why I mentioned it in that context.LameLefty said:"Record a whole transponder" is kind of a loaded phrase; it's so ambiguous and technically imprecise that it could mean almost anything. For instance, I have 6 locals carried in HD by Directv spread across two physical transponders. With 5 tuners, the HR34 could certainly record all the channels off of one of those transponders and be accurately said to be "recording the whole transponder."
The Hopper's exclusive feature, PrimeTime Anytime, gives you instant On Demand access to your favorite shows on ABC, CBS, FOX and NBC in HD. Over three hours per night of HD primetime programming are available to you On Demand anytime for up to eight days from the initial air date. You'll have instant access to the best primetime programming without having to set timers or using up your personal DVR hard drive space. Plus, you can save your favorite On Demand primetime content forever.
On Demand in the sense that the previous 7 days of PrimeTime is already recorded and available to watch "on demand". Local HD channels are required. This is not VOD via internet.Steve said:

The key is that the channels are all on the same transponder. That is the only way that one tuner can record them all at the same time. I wonder if the PrimeTime Anytime tuner is unavailable from 8-11 for any live viewing. The Hopper box may be limited to two live tuners during primetime, while the PTAT tuner is busy recording the big four's feeds.dpeters11 said:But if it's not via Internet, how can one tuner tune to four channels simultaneously?

I think this might be a bit simplistic.Davenlr said:Its just streams in a file.
I would add a couple cents.veryoldschool said:I think this might be a bit simplistic.
First, the transponder has a much wider bandwidth.
- not that wide - around 30 Mbps, ie 3 MBps total of TS per transponder, so any HDD will sustain the speed
Second, if the network channels are broken down into individual files, there is a lot of decoding and multiple files having to be stored at one time.
- nope, not necessary at all, that TS [transport stream] processing fine during direct viewing, so - read whole TS from HDD and send it same way as normally;
Third, if the tuner does have the bandwidth, and not the decoding chips, then the whole encoded [muxed] transponder is one big file.
- sat tuner by design has ability to cut just one transponder (mux after demod chip); no need to decode it - all info for off-line decoding in the mux - save it and reuse later;
Fourth, to play back, the whole "file" needs to be separated [with a tuner?] into the single channels and then decoded.
- nope, tuner and demod (modern time it's combined in one physical chip like BCM4505/6/7) are not using for process stored TS of whole mux (all video/audio/system PIDs), the TS file would be 'pumped' to main chip (like BCM7420 in Hopper), parsed, decoded and separated by user request for viewing and stored separately.
Back to the topic of "can the HR34"... with "only" three dual tuner chips, nope.
