Hi all

In an effort to assist those trying to solve the freezing bug futaura suggested that anyone who's suffering could post the transmitter they're on.
I thought it might be an idea to start a separate thread to isolate it from the general bugs thread.

So I'll go first

Winter hill

With 3 or 4 freezes in each and every hour programme.

I know pee_bee posted on the bugs thread too so,

Malvern

Any more please post here. The more info gathered the more help it should (hopefully) be.

Cheers. Tom

"Have taken the plunge and replaced my ailing Bush T7650 with a Hitachi HDR 5T01 (T7655) at the new reduced price from Argos. First impressions are positive overall but, as half expected, it does have the freeze issue on playback. My very first recording was last night's Springwatch and on watching it back later on it froze once in the one hour programme. Do hope they will correct this."

This is an extract from my post on the Bug List thread. As requested by Futaura, I am now posting to this thread to confirm that my transmitter is Winter Hill.

A brief comment on my experience - it froze many times in the past, but only very occasionally. Once every week or so, certainly not several times in one hour as Tom has been getting. This is on Tacolneston and I have not seen the issue at all since the end of April, despite trying everything I can think of to trigger it.

Several days in now with my Hitachi T7655 (Winter Hill) and am experiencing at least one freeze on every playback. Just seen it twice in the first 10 minutes of a one hour BBC1 HD recording. As there seems to be no news on the timing of an upgrade it looks like it will be heading back to Argos as faulty.

Shame really as I have loved my last 2 Vestel PVRs and haven't a clue as to what to replace it with quality and price-wise.

Easy for me to say, I know, but I'd stick with it - I'm sure it will be fixed one way or another.

I'm keeping mine, just as well we've got a perfectly working flawless 7650 to use while we wait for the fix

Cheers. Tom

I'm the proud owner of a Bush T7655(demoted to bedroom) and like the other posters here it suffers from the freeze issue, at it's most naughty it can freeze up to three times an hour and at it's best it can go weeks without an issue. I tried both the sudbury transmitter and bluebell hill transmitter but the issue persists


Incidentally my parents got me a TV and Hitachi pvr from Argos which is almost identical to the Bush even the remotes are interchangeable and so far months later no freezing.

So, you have a Bush and Hitachi in the same house and only the Bush freezes? Can you confirm the software version that each is running?

Most defiantly I have run both the Bush and the Hitachi on the same setup and the Hitachi does NOT appear to have the temporary freeze issue on playback

Not sure if this is what you ask for but in the Bush Settings/Configuration/Receiver upgrade/ UK-v1.21.3 and also in the same place the Hitachi says UK-v1.21.3 the same

It just seems the Bush occasionally struggles to read from the disk and stops for 20 SEC's or so. I have just been recording two program's at once while playing another on the Bush to see if I can make the HDD fall over but it performed all three operations perfectly. So I don't know it's a weird intermittent problem with the Bush.

Unfortunately, the issue hasn't been fixed yet. It seems there could be several ways to trigger the problem - in particular, if you happen to use the 120/30 second skip or rewind/ff buttons at the wrong time (while the box does some housekeeping every 60 seconds, and especially if the playback banner is still on screen). That's when it happens most for me, but occasionally it will just freeze without the remote having been touched for at least 30 minutes. Hopefully, it is all caused by the same underlying issue (which incidentally Broadcom should be looking into).

Just out of curiosity, why did Vestel change to the broadcom chip from the Sony of the T7650 model?

Cheers. Tom

Ok, to clarify - all Vestel HD recorders are powered by a Broadcom chipset (SoC / System-on-a-Chip), and it may well be the same type in all. The T7300 and T7650 use Sony's DVB-T2 demodulator chips (the only option available at the time), and later on Broadcom produced a DVB-T2 demodulator which the T7655 uses. The demodulator chips (one for each tuner) are separate from the SoC (essentially the CPU). Don't know the reason why, but suspect cost may have been a factor and perhaps it was more preferable to stick with Broadcom solutions throughout. Obviously, Broadcom supply various driver software to manufacturers like Vestel and Humax.

I don't recall having the freeze issue with the Amber software on the T7655, but I was not a fan of that for other reasons - skipping, jumping and stuttering, but at least that went away with the Emerald software.

Was just wondering if the chip change had anything to do with the freeze issue
Maybe not then........
