Advertisements How much or by what percentage can Tivo HD programs be compressed with a typical compression program utilized by a thumb or pen usb drive? The reason I ask is I am considering the purchase of a pen/thumb drive, but I'm not sure which size I need. Since a typical 1 hour hd program falls somewhere within the 3.5 to 6GB range, if I want to put two such programs on the thumb drive, I would need a 12GB thumb drive to be safe. But.. if these Tivo files are compressible, then perhaps I could get by with a smaller size drive. But how small? Simply put.. how much can the Tivo files be compressed? Btw, I assume I want to do this in their native format, without any type of conversion. But if it makes more sense to convert the files first, then tell me.
