Hi. I bought the 80GB, because i have an 320GB HDD on order, I hope it works. Anyway the manual i received with my DVR is for a newer firmware version V3.4 and my box is only V2.4 Their is a feature to start the recording earlier and finish it later in the manual but that only on V3.4 firmware and my V2.4 does not have that option It seems a bit stupid to supply a manual with menu options that are not in the DVR you bought. I suppose i will have to wait for a new firmware download. This machine is sold under a number of names, daewoo, sharp, hitachi, ect some can only record 1 channel at a time, some can record 2. regards John. John.
