Le choix des touches pour faire certaines opérations est un peu bizarre, mais il y a un aide-mémoire au bas de l’écran et on finit par s’habituer. La réception des chaînes est bonne et l’enregistrement fonctionne bien sur un disque dur et certaines clés USB. Utilisez une clé comme Sandisk Ultra ou Extreme qui ont une vitesse d’écriture plus rapide. Il y a 2 fonctionnalités sur mon autre DVR qui manquent sur celui-là.1. Sur l’autre DVR, il est plus facile de sauter les commerciaux, car il y a une touche avance-1-minute et une touche recule-15-secondes. Ces 2 touches rendent le saut très simple. Sur le Mediasonic, il faut appuyer plusieurs fois sur avance rapide, surveiller, puis stop, puis marche arrière etc. Il est plutôt difficile de bien voir où on en est. 2. Sur l’autre DVR, l ‘avance rapide monte à 300X contre 32X sur le Mediasonic, ce qui est ennuyeux lorsqu’on a une heure ou deux à sauter.

On the odd chance that you're using a drive that was originally internal (i.e., "naked" drive), be aware that this device cannot create partitions. It can only format. I almost returned it until I figured this out.Most people will use an external drive, so no problems there, since these are usually pre-partitioned and pre-formatted. However, if you find that the drive disappears after every time you power off the device, connect it to a computer and partition it there, then reconnect to the PVR and format.Otherwise, it works as you would expect. Like others have stated, it can be a bit sluggish when changing channels or switching to USB from tuner.To set the timer, I usually go to the channel I want to record, then press EPG to call up the guide. It only shows 12 hours. I don't know if this is a limitation of the device or from OTA data. However, you can set the date/time manually. If you set it via EPG, it is not "smart", in that it doesn't know when the program actually starts and/or ends. I usually manually adjust the timer so it starts 5 min early, and since I record sports, I set an extra 30-60 min in case the game goes over(time). The PVR will turn on when it is supposed to and turn off when the recording is done.A couple of gripes: LED display is really bright, and I wish there were a USB port on the back, so a "permanent" hard drive sits out of the way. PVR gets pretty hot, so make sure it has room to breathe.3-stars because there's nothing special about it, but there's nothing really bad about it. I would recommend it for casual use, but you may want something better if you do a lot of recording.

This picks up digital and HD channels if you only have an antenna, so great for the cottage or where there is no wifi to stream

This has a great guide and was so helpful in finding the best position for my antenna. After doing a channel search hit the info button twice and it brings up the signal strength. You can then move the antenna to find the best position. It comes with a great remote, a nice tv guide, and is very easy to set-up and navigate. The only thing is the remote must be on the same signal as my Vizio sound bar as it changes the input when I hit the guide button, oh well. It is a fraction of the cost as some other boxes but does the same job and does it well. I highly recommend this product!

High quality tuner. The signal quality meter (press INFO button twice while watching a channel) helps determine the best antenna position for precise placement. Remote sensor works well. Unit is responsive.Takes a bit of time to power up (about a minute) but once it’s running it works well. Didn’t test the DVR functionality as I don’t need that. I noticed the power plug was a little difficult to plug in/out of an outlet, not sure why.Overall a good product and the price is a little high for what you get (~$40) but if the product lasts a year or more it’s well worth the cost.

Have been using this for a month or so. In general, I am happy with it. As pointed out by many, the user manual isn't much. On the positive side, it gives you an idea of it's features. On the negative side, it doesn't tell you how to use them. However, with trial and error they are not hard to figure out. The picture quality is great and the record function works well. One negative on the record function is that you can not watch a pre-recorded program while recording another. You just have to plan around this. Only other slight negative is the remote is weak. Ends up like the old days when you had to point the "clicker" at arms length towards the device. In general, and considering the price, I am quite happy with it.

I wrote a nice long review.. and poof. UGH. OK.. Tuner works great! The DVR or rather a PVR saves to usb, and its in a format it can play on PC later. The antenna signal strength meter is very handy and the tuner is very good. How they sell this for 40 bucks is amazing. I wouldnt hesitate to buy another one.electronic program guide comes over the antenna, it doesnt connect to the internet. which ias a good thing to me. It transmits old analog to a older tv or HDMI using a computer monitor. it just works. The menu system is light, easy and to the point.But the antenna signal strength is the main this I like the best. Picture attached.

I got this to replace a failed TV tuner on my Smart TV. I does the job, and works. It's nice that it has a record TV function to USB drive. I suggest you get a flash based external SSD for best performance with it's own external power, but not required. TV guide layout is a bit bad. Instead of a horizontal left to right layout showing multiple channels per row like a normal guide, you get a vertical list layout and it only shows one channel at a time. The picture quality is bad, and the menu doesn't have much adjustment settings. It looked overly bright and washed out. I ended up replacing motherboard of TV to fix my tuner and I returned this product.
