"appareil trop lent"

Hello,

I recently got a flat-screen TV and can no longer use my VCR... However, since I often fall asleep watching TV, I used to record my programs to watch later. The problem is that I plugged in a large USB stick (more than 150 hours of capacity) into the "demodulator" to receive TNT channels, but I keep getting a message every 30 seconds: device too slow... something like that, and although it records, the image stops and jumps for 2 seconds every 30 seconds.

According to my research online, it's the write speed that's not high enough, and it works with some USB sticks but not others.

If I buy an external hard drive that I connect via USB to the TNT demodulator, will that eliminate these bugs and allow me to record normally?? If so, what specifications should I look for to get a good model at a good price??

Or do you think an even larger USB stick would suffice?

I would like to take advantage of the upcoming Black Friday to make this purchase, so I hope to get answers quickly :)
Thank you

Configuration: Windows / Chrome 62.0.3202.94

    Hello,
    Indeed, many PVRs "digest" USB drives poorly due to writing/reading speed ("device too slow")
    Get a branded hard drive but do not exceed 500GB for power supply reasons, that is to say, 500GB = about 50 hours of HD recording... ;)

      Good evening Andy and thank you for the quick reply.

      I don't understand the story about the 500 GB and the power supply, could you explain it to me? Thank you.

      External hard drives require power supplied via USB, and beyond 500GB (1TB for example), the amperage is too high to be delivered by a power bank (it works on a computer); otherwise, they need to be powered separately...

      Okay. If I opt for an external hard drive that needs to be plugged into a power source, that would work (which would be connected to the TNT decoder via USB).

      500 GB = about 50 hours in full HD, isn't that enough for you?

      Given the number of video tapes I still have, accumulated because I haven't had time to watch them, I'm a bit worried lol, knowing that I often wake up at 2 or 3 in the morning after having pressed the record button around 10 PM... so with so many hours several times a week, I'm afraid I'll quickly run out of space if I can't watch them in the meantime :D

    Hello,

    In USB drives, there are several class categories, the most important and expensive is their speed... in class 10, it can go up to 100 euros... the subject should not be overlooked... Let's add that the sellers know nothing about it, sometimes even ignore the existence of these classes...

    It should also be known that recording in high definition is much more demanding than standard definition... In my opinion, a recording in 720p often does the trick... it takes up much less space and is not as demanding in terms of response time.

    Not all devices can do it... But it is sometimes possible to receive a broadcast in 1920x1080 and record in 720.

    Normally, a USB hard drive that spins fast enough should solve this problem... A 5400 rpm or better yet, a 7200 rpm.
    You need to make sure that the USB port supplies enough power to run it; otherwise, it needs its own power supply...

    Here is an example of a 2.5" and 500GB powered by USB

      good evening jeannets

      thank you for this additional information.

      I think I will therefore go for a high-capacity external hard drive (maybe 1 TB) that connects to the mains.

      thank you both ;)
