Thanks for the "fix" by giving the exact date of 31st July 2012.
I do have some personal opinions about your serious macro-blocking and pixelation issue with your Byond PVR.
Remember, whatever comments below are only my "non expert" opinions based upon what I thought is logical and may not be accurate. Just for discussion purposes only.I do agree with the others who have advised that you call Ast Cust Supp to check your Byond PVR and replace whatever parts found to be defective.
There is ONE important and obvious difference between (1) the firmware/software operating system installed in the Byond PVR and (2) the software and operating system installed in the computer... and this is... Byond PVR users
cannot make full configuration setting changes, cannot install and uninstall software such as codecs, mediaplayers, choose whatever to be installed.
From the link you gave, the explanations on the "pixelated faces" relates to the HTPC (Home Theatre Personal Computer) which allows users a much higher level of control to the choices of configuration and settings changes to the codec, drivers or software installed and include the ability to choose and change to whatever hardware decoder cards used.
I believe that such macro-blocking and pixelation issues can be caused by 3 important factors...
1) Interference to the signal path to the Byond PVR causing a serious drop in signal strength or corruption such as bad weather, poor cable connections, mis-aligned LNB, etc.
2) Too high video compression and too low video bitrates used.
3) Fault caused by firmware/software and/or hardware from the Byond PVR. This included the codecs used, harddisk problems, etc.
Yes, factor (1) can cause such issues due to weather but its NOT possible to 100% happen all the time which your PVR is exhibiting. For factor (2), I believe a very very high lossy MPEG compression combined with very low bitrates is needed in order to cause such serious macro-blocking and pixelation issues from your PVR BUT I think Astro will NOT use such extremely low quality video because they will definitely face complaints and "fire" from 100% of their subscribers including myself !
If the signal is still strong, then cable connection and LNB should NOT be causing such issues. Then what is left is factor (3) which needs to be checked whether its internal hardware is faulty or not. I don't think its the software codec bug in Version 7.0s because IF it is, then the same issue will occur in everyone's Byond PVR, not just your PVR only.
I contacted my installer friend for his feedback on the Byond PVR (with internal 500 GB harddisk) and he told me that he had been called many times to check many PVR sets after complaints were made. He found many PVRs were found to have "problems" and replaced them but he cannot tell me what the various faults were because he just returned the faulty PVR to the Astro service department. Such "incidents" were quite high, even happened to PVRs installed less than a month.
There is another PVR type used for school installations, the Byond X-Plus which also can record to its 500 GB internal harddisk BUT have only 1 tuner. Here is a photo...

My friend also told me that he had never replaced any Byond X-Plus which he thinks is somehow better than Byond PVR. Mmm... I think better maybe because of less usage hours in schools and less harddisk stress without "instant replay".
Please bear in mind that I cannot check or verify what my installer friend said is true or not.
Anyway, true or not, I suspect the most likely possible fault is usually the internal harddisk. For our computer, whenever we saved any huge files (many gigs), the reads and writes to the harddisk lasts only a short while, maybe a few minutes or more and most of the time the harddisk goes to power saving mode with the disc platters and heads remaining idle. I believe the situation is different for the Byond PVR internal harddisk. This is because of the "instant replay" of any channel being watched, which the PVR is actually buffering the video to cache memory and then records at short constant intervals. This continues as long as the PVR is still on. Imagine the constant harddisk read and write activity continuously for many hours everyday which I believe many many times more stress, wear and tear put on the PVR harddisk when compared to the harddisk inside a computer ! Maybe the PVR engineers do implement some method which help to reduce harddisk stress so I don't know BUT I suspect any such "method" if any, is not working. Even the internal fan to reduce heat may not be enough. Well... only my opinion.
To be fair, I believe the same stress issues can also possibly happen to many other "non Astro PVRs" with "instant replay" function.
I connected my Byond (non PVR) HDMI directly to my LCD TV, not to my Yamaha amp. Switched to HBO Ch 411 (SD) and took 2 snapshots using my 8 MP phone camera and shown at actual size (no resize or edit). May take a longer time to load due to the size.

Enough said.
Anyway, I would like to know what you and others think about my opinions here so I welcome any feedback. Thanks.
