If I record an SD show on an HD channel, does it take up an HD sized portion of the hard drive or an SD sized portion?

Take, for example, the Lewis Black special on HBO. It was in SD even on HBOH channel 70.

yes.

 

[superunlikely]

Yes which?

 

[matto]

Yes to your question, "Does SD show on HD channel take up HD-like space?".

Oh I guess you were answering the question as I posed it in the subject line.

Thanks.

The recording is the raw feed from the satellite requiring subscription and channel authorization to play back.

There are a couple of counter acting factors. Standard sat channel in MPEG2 are lower res but MPEG2 has less compression then the MPEG4 used for HD and local channels in HD. I still think a regular SD program on an MPEG4 HD channel may be less storage then a true full 16:9 HD.

When Local HD's software finally arrives the OTA HD will be HD in MPEG2 so they will consume more storage space then the HD from satellite. I expect them to be saved as raw feed also, known as .ts files.

the lack of pixel change in the pillarboxed areas of SD in HD will give you some space savings, but it will be on the same general order of magnitude as any other HD recording.
