How do you come to such values? DVB-broadcastings have - depending on
the audio-streams - about 3,5 MBit/s -> 2h 50min on one 4,7 GByte
DVD-R(W) and there's starting a dumping-price war between DVD-/+R(W).

Additionally, the PS has time-stamps which would make the index-files
superflous for searching.
