VIP 622 & Mpeg4 recording

[Trek2000]

I have a VIP 622 I recorded 4 hours and 16 minuets of HD movies. I presume they where Mepeg4. They only took 1 hour 47 minutes of my recording time. OTA HD takes up one hour for each hour recorded. Does that mean I can record over 60 hours instead of 30. If every thing I record is Mpeg4?

MPEG-4 is much smaller than MPEG-2. OTA is MPEG-2. The recording time is really based on MPEG-2 time. Dish's MPEG-4 is about 2x as compressed as MPEG-2, so you can usually record 2x as much for the satellite programs.

I think it was "Smith P" who did some analysis of MPEG4-only recordings and yes, ~60 hours was a number I recall.

Are Locals on Dish Mpeg-4 or Mpeg-2?

 

[garys]

Local HD supplied by Dish are mpeg4 (although some were mpeg2 when they started). OTA locals are not compressed.

Technically they are compressed, just not any more than they need to be to fit in the channel by themselves. (Or if they have subchannels, more than that.)
