Shrink won't compress "Beyond a Reasonable Doubt

[Lame]

I've ripped Beyond a Reasonable Doubt with DVDFabHdDecrypter ver 6.2.1.6. When I try to compress it using DVD Shrink my computer shuts down totally when there is 2-3 minutes left. I've never run across this before; does anyone have any ideas?

If your computer "shuts down totally" there must be something seriously broken with your machine :eek:

Even if DVD Shrink was unable to handle that specific DVD, the application would crash, freeze or simply produce bad output. But an application, which is running in "user land", cannot crash the entire system!

However DVD Shrink will put high CPU load on your system for a long time. So you should check your CPU temperature while using a tool like Prime95. Also check your RAM with Memtest86+.

Unless "Run analysis and backup in low priority mode to improve multi-tasking" is checked under preferences.

Wrong. Running a process with "low priority" means that other processes are preferred in situations where more threads/processes are ready to execute than CPU cores are available.

Or in other words: With "low priority" DVD Shrink will never use any CPU time that could have been used by another (higher priority) process. But it won't prevent DVD Shrink to use all the "unused" CPU time!

So unless the CPU load is 100% already, even "low priority" processes will get CPU time to execute. Any if no other process is executing, they will even use all CPU time that is available ;)

(BTW: That's the same reason why "High Priority" doesn't make an application any faster, unless there are many processes ready to execute)

Even with the PC being idle, it feels more responsive when starting programs, switching windows or so with this setting as without so I think it makes a difference.

...which doesn't change that fact that you'll get ~100% CPU load for a long time with DVD Shrink running, no matter what "priority" is set - unless you are bottlenecked by I/O.

And heavy CPU load can cause a badly cooled system to crash (or "shut down"), even if it seems to be "stable" under normal usage.

The same way bad RAM can cause random system crashes. However applications that process a lot of data (e.g. DVD Shrink) increase the chance that bad RAM triggers a crash.

So my advice: Make sure that the RAM is okay (with Memtest86+) and check whether the CPU is running stable/cool under long/heavy load, e.g. with Prim95 stress test.
