What Dan said.
Something that will be unclear to some readers is just how many channels they think are digital are actually analog. Chances are, if your local cable company has a large number of channels in analog and also in digital, that they will not duplicate the channel as a digital signal. Sure- it will have a different number, but it's still analog. My cable provider is Time Warner, and where I live, about 90% of the channels in the non premium tiers are still analog. So in my case, enabling "Just" analog will be almost identical to full enabling of TTG/MRV. For others it will mean less. Your mileage will definately vary- many major metropolitan areas are nearly all digital but you can check if all you have is a cable Set top Box. (for Motorola boxes here
for Scientific Atlanta boxes here)
. If you have an S3, there is an easier way to spot check as you will see in the same thread.
Anyhow- Dan's response is the authoritative response, but I composed a response last night but neglected to send it. For what it's worth-
Not supporting TTG or MRV on the S3? That's about as likely as Apple deciding to stop supporting the Mac OS and shipping computers with Windows instead.
I'd be stunned if by year end they don't have TTG, and MRV working for all analog and OTA including HD, as well as HD and SD TivoBack.
There might be bonuses that would be really really cool on top of that- like TivoBack support of MPEG4- effectively allowing you to store a thousand movies on a 2TB S3. The cool thing would be to use the PC to compress shows on the S3- eg. have it take any Keep until I delete, move it over to the PC- compress it to MPEG4, then replace the original. It would effectively triple or quadruple the hard drive capacity of the S3.
Maybe not in the first rev, but Tivo will do it because the machine can support it. It is inevitable that the prices of 1TB drives will come down and when they do, the universe changes because everyone will have these ginormous libraries on the S3. This will take video consumption patterns to a whole new level. For one, HBO, Showtime, PPV and VOD will become increasingly irrelevant to viewers who have larger choice of shows they care about available on their S3. The nail in the premium tier coffin is that the S3 shows are free.
But yeah- you say- that only works for analog. Well- No, because if cablelabs digs in their heals you know what Tivo could do? Functionally, if the S3 could record from an STB via an analog connection, it would be ok to TTG and MRV it. But the S3 doesn't need a digital STB. The S3 has it's own decoder and already produces an analog signal. So as silly as it sounds, an new rev of the S3 could simply take the analog output of the decoders, send it into the encoder for an analog channel and voila- you have a stream of data that you can TTG/MRV- including SD versions of HD shows. Everything that doesn't have copy flags. Note that this could be done at TTG/MRV time. The downside is that this would require the use of the decoder that is normally used for playing so this admittedly unlikely scenario, so maybe they put an analog input on the back of the S3 along with some IR blasters and call it a day.
