I know this is way outside the DIY remit and should be posted to HiFi
dot something but I after sensible replies rather than baffling technospeak. Thus, your indulgence is craved. My aged father is proposing to celebrate (sic) surviving the recent fitting of his pacemaker by the purchase of a DVD recorder. Neither he nor I have any understanding of the pros, cons and meaning of all the plus and minus stuff when it comes to choosing these beasts. Can anyone shed any light on how to choose a DVD recorder? Does it matter if it will record in only one of the + - formats??? Should he simply buy Richer Sounds' latest best buy????

Thank you Richard I have a Panasonic DVD-R that I bought about 18 months ago. It works very well. It is well worth shelling out for one with a harddisk if at all possible. Most stuff you can record to that, and then transfer it when you know you want to keep it. The only problem I have had is with cheap disks. As long as you buy good disks (TDK etc) you will be fine. In reality, I don't think it really makes much difference whether you get DVD-R or DVD+R. This is a good place to start: http://www.dvddemystified.com/dvdfaq.html -- Remember that you are an Englishman, and have consequently won first prize in the lottery of life" -Cecil Rhodes "For a century and a half now, America and Japan have formed one of the great and enduring alliances of modern times." George W Bush -Tokyo, Japan, Feb. 18, 2002 Happy shall he be, that taketh and dasheth thy little ones against the stones. Psalms 137:9. Behold, I will corrupt your seed, and spread dung upon your faces. Malachi 2:3. "He who rises up to kill us, we will pre-empt it and kill him first," - Ariel Sharon 8th May 2002 |

if it will record in only one of the + - formats??? Should he simply buy Richer Sounds' latest best buy???? There's a bunch of DVD background here : http://www.videohelp.com/dvd May help you choose, but you probably need to forget formats go for ease of use. Go to one of the sheds and get a demo then buy cheap off the internet. Rgds |

Format doesn't really matter but buy one with a hard disc and then it really doesn't matter. If you can get one that handles analogue and digital transmissions so that you don't need to buy it it's own STB when the analogue turn-off happens. |

: Format doesn't really matter but buy one with a hard disc and then it really doesn't matter. Absolutely - the convenience of a hard disc is amazing; just press a button to record, no finding a disc, etc. I've got a 250Mb; I do a lot of timeshifting, but that's turned out to be an overkill, figure 1 hour to 5 Mb at standard (excellent) quality, 4 times that at better than VHS quality. You can start watching something before you've finished recording it, or watch something while you're recording something else. They will all also record to DVD disc, so you can archive, or use re - recordable (RW) discs for further storage if your hard drive is filling up. A CD(R) is recordable on; A CD(RW) can also be erased and used again and again like a VHS As for +R(W) and -R(W): -RW is later and better, but +RW will do fine for home recording, and will play on just about every sort of DVD. If you can get one that handles analogue and digital transmissions so that you don't need to buy it it's own STB when the analogue turn-off happens. I personally wouldn't get a digital ready one yet, IMO digital TV isn't ready for prime time yet, and for most of us the box will need replacing anyhow before the switchoff. In the meantime a 40 quid STB will do the job HTH mike |

But good 80gig ones are sub 300 now, and I wouldn't be frightened as I was before personal experience of using long play - it's far better than VHS or TV itswelf now the authorities are crushing bandwidth. mike |

I would strongly recommend an HD/DVD recorder if finances stretch to a bit over £300 You can watch and then delete, you have delayed playback (i.e. you can pause and then watch e.g. 5 minutes behind transmission time in the event of an interruption, you can write similar programs (e.g nature or comedy programs to a particular disk), you can edit - they are much more flexible I have a Toshiba RD-X32SB and it does the job, I'm quite pleased with it -- geoff |

Analogue signals are much more robust than digital. The detection signal strength of an analogue radio sound signal for understandable reception is IME almost x10 that of a digital signal! That rather depends on the system used but for analogue versus digital television you are correct as the modulation scheme is really only suitable for stuffing bits down a piece of wire with little crosstalk (and even then there are cheaper better options). But if you remember the old analogue mobile phone system you'll see the digital system is far more robust. In fact the CDMA modulation schemes used in 3G are about as near as one can get to the physical limits of a channel. |

If the recipients mail box is full, it will keep trying and eventually bounce back. If the recpient's mailbox is full, the server should return a 552 error. All 5xx errors are immediately fatal and preclude a retry, so the mail shuld be bounced straight away. That is not, however, the situation to which I was referring. -- Bob Eager begin a new life...dump Windows! |

The detection signal strength of an analogue radio sound signal for understandable reception is IME almost x10 that of a digital signal! Try measuring the speed of a 2.4GHz network to see how prone to interference digital becomes throughout a day! Depends on many things. One example is NICAM sound. It will still be 'perfect' with obvious picture problems. Of course when it does 'go' it doesn't do so gracefully. -- *Rehab is for quitters Dave Plowman London SW To e-mail, change noise into sound. |

:::Jerry:::: wrote: So do explain why mail can be returned to the sender up to a week after the mail was sent to a invalid and non existent address...... If the email was sent to an invalid, non existent address and took a week to bounce then the mail server is broken. If (as others have said) it the domain is valid then the mail system will attempt to deliver it to the mail machine(s) at that domain. If the address is invalid then ideally the remote machine should not accept it and should reject at SMTP time with a permenant error (5**) to cut down on collaterol spam but several systems out there are broken and accept and then bounce. Should still be pretty instant though. If the remote mail system accepts the email and then takes a week to bounce it it must have been sent to an address that is valid (many domains run catchall addresses for example). A mail system will not keep retrying a non existant address for a week - it has nothing to retry! (unless it is very, very brain dead). Darren |
