I am considering getting a Hauppage 1212 External PVR
Top quality for video is 13.5 MBPS.
How much space would a half hour TV program in HD take up?
I am considering getting another external hard drive just for the PVR.

...ok let me just take a stab at this one.

13.5mb per second? Is that right?

30min x 60 sec/min = 1800 seconds.

1800 sec x 13.5mb/s = 24300mb, or 24.3 GB.

Wow that was tough!

Is that 13 MB a second or 13 megabit per second?
Reason I am asking is two hour movies on blu-ray at 1080 P are not usually more than 10 Gigs.

I don't know, but yes that does seem absurdly high.

Let's see if I can help..

13.5 Mb/s = 1.6875 MB/s

1800s x 1.6875 MB/s = 3037.5 MB (3.0 GB)

Sounds about right. My 1 hour 1080i HD recordings are ~8 GB so I expect a 30 min program should be about 4 GB, depending on the bitrate. Blu-rays can vary in bitrate up to over 40 Mb/s as they (1080p source) have double the frames as 1080i (I think??:)  )

Yeah if it's megabits instead of bytes that's right. Wonder why they would list it as bits tho... Bigger numbers sound cool I guess? =P

Here's an actual data from my Hauppage 2250 on HD recording...

An hour of HD TV (1080i) recorded is ~45Gbyte.

I recorded Superbowl, Grammy Awards Night, FIFIA Finals... The recorded files is between ~25Gbyte to ~27Gbyte.

I use one of my PC as my DVR/PVR..i Allocated 2Terabyte space for it so don't worry about space.
