This is the thing though, seems to be Virgins baby...the more services the better and its getting to a point where pumping so many services down the one line is getting too much for alot of cable...its noticeable alot more nowadays...hits taking a while to reach boxes...i think its time for fibre optic cable to be run straight to the customers home...with a small wireless sender that is recieved from a small reciever at stb's and modems :D

ONE CAN ONLY DREAM :)

Wonder if they'll ever get round to using MPEG4 instead of MPEG2. Requires much less bandwidth for the same quality! (apparently) :)

Anyone know if they've thought any more about this at all?

Mpeg 4 figure on 1TB HDD is 240hrs HD
http://www.sky.com/shop/boxes/1TB

Not sure on Mpeg 2 for TIVO.

Half that if VM's own figures are correct. Bring on MPEG4! (The incompatible boxes could be replaced with the rejected-because-of-TiVo Samsung boxes?) Who knows.

Even on mpeg2 TIVO's 1TB is more than enough for everybody. But I agree mpeg4 would be better.

True. Roll on April! :D

there is a page in the settings for tivo that should tell you roughly the amount of recording time remaining. instead of guessing lol.

I cant see many having issues on a 1 TB HDD LOL :D

It depends on the bitrate of the hd being recorded. Sky can give you 240 hours at a bitrate of 10 Mb per second. Blu-ray is 40 Mb per second.

Now every channel and even shows within a single channel have a different bit rate so hours of recording can only ever be an estimate. i think this is why we see so many different recording hour figures

For anyone who's still not clear on the padding/recording priority, this is how I believe it works currently with 2 tuners.

We'll assume we are recording 2 shows at 21.00 with 5 mins padding on each. If a recording is scheduled at 22.00 then there are two possibilities.

a) If the 22.00 recording is a higher priority than either of the 21.00 shows then it will clip the padding off one of the 21.00 shows
b) If the 22.00 recording is a lower priority than both 21.00 shows then the recording will not start until 22.05

Recording priority seems to be:

1. One-off recordings
2. Series links (in order specified in series link management menu)
3. Tivo Suggestions

Suggestions get 10mins auto padding on stop time. Everything else you have to set.

With 3 recordable tuners it should be fairly unusual to get a problem, fingers crossed.

Where is that option? All I see is a recording capacity estimate of 99hrs hd 325 hours sd. This dosnt change and dosnt show estimated time left.

TV is broadcast in 1080i meaning a picture of 1440x1080 is broadcast, much less information that full 1920x1080. Plus a Blu Ray compressed to around 13mbps would hardly be noticeable, so 10mbps for Live TV is essentially as good as it will get.

My point is you cannot just look at recording hours alone. Sky could record 480 hours of hd at a bitrate of only 5Mb/s. More hours of recording for a fixed hdd size and compression algorithm results in lower picture quality.

Now when you have different compression algorithms it just gets impossible to compare.

Which gives a higher quality video stream 10Mb/s mpeg4 or 24 Mb/s Mpeg2? I dont know the answer. If skys figures of 240 hours are true and Virgins figure of 99 hours are true, then these are the two things to compare.
