Windows 7: need help in tracking a media playing issue

when it happens its not usually running as its not set to start with windows.

Check your processes in Task Manager to be sure, maybe you'll see something else too. Those board utilities can run processes with the program interface not.

PxHelp20 ---> PxHelp20.sys Windows process - What is it?
You may have one of the programs installed, that uses the driver.

lm reasonably sure its not running, however will check next reboot.

that being said l found two other peeps experiencing the same issue.

Some MKV Files is Freeze once Per Boot
Some MKV File is Freeze once per Windows Boot

two different codec packs as well, the second site makes the codec pack l use and he experienced it with a previous codec pack he used.

@Jacee
looks like winamp is the issue on that one going by the link you posted as l have winamp installed.

lve updated my graphics drivers, so far l dont see any dcom issues.. furthermore the first mkv l ran didnt freeze the system. however l wont count my chickens before they hatch quite yet as it didnt always freeze however l opened the largest mkv l had on system with the highest probability of causing an issue (one which l believe l might have tried before to create the issue).

the definitive test will be seeing if it happens on my next reboot. l will give it a week or two and hopefully remember to report back.

just an update, three reboots after updating my gfx drivers and the issue hasnt reoccurred at the moment so lm hoping lve pinned down the issue as usually lve had one or two freezes by now.. hopefully lve found the culprit but will continue to monitor.

I suspect thumbnail generation.

When you installed MPC, did you choose to let it generate video thumbnails?

I always disable all of the video thumbnail options, because of the time wasted generating them.

its not, most of the video files l use are mkv files and lve never set it to generate thumbnails. however when the problem happened it was when opening an mkv file and always the first one. however lve been testing with and without certain things running like the Asus probe program etc. so far since updating graphics drivers it hasnt reoccurred and ld say lve rebooted maybe three times now, generally ld have had at least one or two freezes by now as lve specifically been aiming to play mkv files before any other file type in MPC/MP video players to create the issue and so far weirdly l havent had any problems yet however a definitive result would likely be waiting a week or as technically it was an intermittent issue which happened more times than not.

I posted my last comment as I was reading through the thread.
Obviously that was before I read your comment about the graphics driver update.

I get MPC-HC through the K-Lite Codec Pack.
I have to disable the thumbnail generation options, as K-Lite Codec Pack pre-selects many (if not all) video formats.

It's probably about time to check for the latest update.
