RE: Freeview HD PVR - Digital Stream DHR8205U

While I'm on this thread, I have a question about archiving recordings to a USB hard drive. I'm using a 160GB IDE drive in an old IcyBox, and it's incredibly slow, to the point of almost being unusable for large numbers of files. I have measured the copy speed as around 5.5 MB/s using several file sizes. I have tested this drive in its IcyBox on my PC, with both Ubuntu Linux and Windows 7/XP, and I get write speeds of around 30 MB/s. Why the disparity? Is there a problem with the USB controllers in this DigitalStream box? I can't imagine the processing capability of the DHR8205U is the problem, as it can quite happily record two programmes while watching a third. The speed I'm getting is certainly way, way below the maximum USB 2.0 data rate of 480Mbit/s (admittedly a theoretical maximum, but I'd expect to get at least half that in practice).

Has anyone else noticed this, and is there a fix? I'm considering submitting a report to MIT/DigitalStream, but I don't know how to do so (is there a forum? I can only find an email address for MIT), so I thought I'd post here first.

Missed a few here. Firstly, no Sky Player on the box, only BBC iPlayer through the red button.

Secondly, on the USB copy speed, it is much much slower than standard USB speed. I've no idea why this is, but it is (and has been on every PVR with this facility that I've owned).

Doubt you'll get any further on this I'm afraid, but it's always worth a go. MIT can be contacted through this website, or you could post a query on this forum which has a number of knowledgable types who might actually know why the copy speed is that slow.

Thanks prof, I've posted a message on the latest thread there (currently no. 11!) This problem is becoming a real annoyance for me. I was considering buying a bigger portable drive for transferring programmes en-masse, but 500 GB of files at this speed is going to be ridiculous.

No 5.1 Sound

I upgraded to 4.14r8683-DD on the 23/06/12 as I play via a home cinema set up to get the benefit of 5.1 sound broadcasts however,I noticed I was no longer receiving 5.1 but presumed as my area (Pontop Pike) was being upgraded to digital TV at that time I associated the loss of 5.1 to engineering work but, switch over completed, I still am not receiving 5.1

I amended the upgrade to 8684-PCM yesterday with DD set to off but still no 5.1 sound on BBC HD channels.

How can I restore 5.1 sound?

How is your Digital Stream connected to the receiver i.e. via HDMI or optical? To be honest, you might be better off posting in this forum, as I don't really keep up with the latest developments on the Digital Stream any more I'm afraid.

Hi Professorhat

 

One very quick question on all my recordings i hit the blu sort button and hit time. All the recordings are now in time order rather than date of when recorded any idea how to get them back to the date time recorded???

 

Many thanks

RE: Freeview HD PVR - Digital Stream DHR8205U

Time includes the date, so they will still be in date and time order. I suspect what has happened is they are now in reverse date order (i.e. with the earliest recordings first, rather than the latest recordings first). Just click blue and choose Time again, and you should find they are then in the correct order again.

Nope, still using the Digital Stream, though the hard disk has packed up at the moment so it doesn't record - it's nearly 3 years old now, so way past the warranty date and all I need to do really is just put in a new one when I get a few moments!

Prof, I haven't installed the last update yet. Is it worth doing ? (I ask because it's a pain to get to the top rear USB port !)

RE: Freeview HD PVR - Digital Stream DHR8205U

Hi,

 

Been very happy with my box, which I bought in Jan 2012. There was a problem in march which was fixed easily by the update.

 

However, I've had problems with my 500GB mini hard drive usb that I have used to copy programmes onto.

To start with it worked fine, I was able to format it ok and copied programmes onto it and could play programmes from it.

However, it stopped working, in that when I plug it in, the box recognises it and recognises how much space has been used, but I cannot see any of the programmes.

I contacted the makers of the DS box and they said it is because they can only guarantee that a usb device will be able to be read if it needs 0.5 amp or less power. Apparantly if it needs more, then it is "hit or miss" as to whether it can read it. Mine requires 1amp!

So I now have a mini hard drive with programmes on that I cannot watch on my box...I tried to look at the disk on my PC but couldn't...but I see there is a way of copying/watching programmes (using Linux?).

Has anyone else had this problem, is there a way around it? (I suppose I can get a drive that only needs 0.5amps and then copy the files from my existing drive using the linux route)!

Thanks

Nice to hear I still really like my digital stream. So that's interesting you can swap hdd do you know what size hdd they can take 3.5 or 2.5 can you use 1tb etc or have you got to stick with 500gb? Cheers once again.

Use a powered USB hub with your current HDD, or replace it with a USB HDD that has an external PSU.

I personally wouldn't use USB powered drives on any STB, their PSU/USBs often aren't upto the job.
