2 HC gui's pop up with RBpro

[ricoman]

Since updating to RB pro 1.23.1 whenever I use it with HC 0.20.0.0 2 HC windows pop up, both processing at the same time. I can't get rid of one, it just pops back up. Consequently what use to take about 4 1/2 hrs. is taking 8 or more hrs. Anyone have this problem and the fix?

That's multiple encoder precesses for you. Disable it from the settings menu.

PS: I'd keep it enabled if the PC is dual-core.

Useful under dual core(quad code too) and for HCenc only, CCE does not work with multiple encoder and other common encoders use the full cpu power anyway.

Thanks, don't know how I missed that (or how it was picked to begin with)

Quenc needs 2 instances to use dual cores too. In my tests it was about 95% faster than one instance.

AFAIK Procoder is the only supported encoder that is multithreaded enough to 100% utilize two cores. Although under XP I found 2 instances were about 5% faster. Under Vista 2 instances were 10-15% slower. This was with 1GB RAM, perhaps with more memory it would be faster with Vista too.

You forgot AutoQmatenc!!!, it uses as many threads as your CPU can give, inturn using 100% cpu power :)

^ Procoder2 also uses 2 threads with 100% usage.

Just for the record, after a new update today, I checked and apparently "multiple encoder processing" is the default. That is how I missed the setting. Considering that not that many people have dual core systems yet, maybe it shouldn't be. Minor thing, but it threw me for a couple of days.

^ i believe its only supported if your CPU supports it.

It defaults to "on" only if DVD-RB senses that your system has multiple processors (the environment variable "NUMBER_OF_PROCESSORS" is greater than 1).

With a P4 with ht enabled I've noticed HC completing the job about 20-25% faster with 2 instances running

If you have an ht enabled P4 I'd check your cpu temps under full load, P4's will slow down once the overheat threshold is reached without warning(unless it hits critical )

You may need to enable hyperthreading in your bios settings.

You may need to enable hyperthreading in your bios settings.
How would I do this? For the record I have a P4 3.0ghz processor, no dual core.

Check the documentation of "your" mother board for steps to enter the cmos or bios setup.
With newer computers it is geneally done by pressing a specific key after you here the first "beep" at start up, which is anouncing system post. If your system isn't so fast that the bootup info passes by to quickly, you will see something like "Press DEL To Enter Setup" on the screen which tells you what key you have to push.
The Delete key is common for Award bios. F1, F2, Esc, and
F10, are the other general choices, for different bios.
It may well be that hyperthreading, is already enabled, but I thought it was worth a try.
Follow the instructions on the screen about how the navigate thru the menus, and look for the "advanced bios features" menu, or something of that nature. Within that menu, search for hyperthreading in the list. There will be instructions on how to save any changes made, and exit setup, which will allow the system to contiue booting into Windows.
If your system is a Dell, Gateway, HP, or such, bios options will be somewhat limited as compared to a non propietory system put together from components.
Hope this helps. :)
