OK. I've installed MediaPortal 1.1.0 RC1 and on a fresh install, I am having LONG delays (as if MediaPortal were waiting for something to timeout). During these delays, MediaPortal is unkillable via Task Manager...until it becomes responsive again.


These delays occur in: Videos, Pictures, anything that has a browsing interface.

I can reproduce this delay, ALL THE TIME by:
1. Opening Pictures from the home screen. Pictures opens the default folder.
2. Pressing "Up / .." a directory to where MediaPortal shows CD Drives and other Picture folders.
3. MediaPortal now takes 30 seconds or more to list the available picture folders and CD/DVD Drives.

I have disabled ALL MediaPortal plugins (except Home and Pictures). I have removed CD drives from the database (and deleted folder databases). Nothing helps.

The log is also very useless.

etc. Nothing useful there.

Again, this is on a CLEAN MediaPortal install. This is even with default config. Are there any fixes in SVN for this!?

Thanks!

How many files do you have in these folders? Are they stored locally or on a remote server/usb-disk?

 

[DigitalDJ]

They are completely empty. The only folders in the database are the ones added by default by MediaPortal. CD/DVD Drives and Users/Pictures. None of which has anything in them.

I figured out what this is...and it is a bug.

I checked out the latest SVN so that I could debug the problem.

It turns out that during this delay, MediaPortal tries to determine which removable drives to show on the list.

This PC happens to have an 8in1 Card Reader, which is obviously has some blocking IO going on when there is no media in any of the slots.

As far as I know...so far...this occurs in VirtualDirectory.GetRootExt(); and Util.GetVolumeInformation(); (i think)
