No, VDR does not send a startsignal. So the harddisc turns on directly before the recording. I can?t say if data is being buffered or if it is lost, up to now I had no problems, so I believe that there is enough buffering. BUT: My second HD goes down after 5 minutes and it is the bigger HD. So most of the recordings will start on the second HD and played back also only from the second disc, so I can?t say for sure if I simply had no problems because most of the time everything is recorded on the second disc. But I already had recordings distributed on both discs, and I have had no problems when I demuxed it, so no packages were lost. J?rg
