DVDs pause and hang

Postby Guest » 15 Feb 2004 16:57

Hi,

I have had VLC running for about two weeks now. So far I love it. It is nice to have one player for ALL of my file types, that runs on ALL of my boxes. I have run into a new hiccup that I can not seem to resolve my self.

When I play DVDs they pause for about .5 sec. Every 1 -2 seconds. I ran top to see if my system resources were being over run. With the DVD playing it showed the processor %50 idle and 180 MB of RAM listed as free. So I am assuming this is not do to a lack of hardware.


I did some reading on the forum and found a listing that talking about making the buffer larger. So I went to Settings > Preferences > Plug ins > access_file and set Caching value in ms to 16000 (the max value). When that did not work I set ALL of the Caching values under Plugins to 16000. It did not make a difference.

I also found a setting under Settings > Preferences > General settings > Allow VLC to run with real time priority. This did not help either.

Since I did not see many other postings on the forum about this I assume this is a problem with my PC and not VLC. Still any ideas would be helpful.

access_file only works for files.
There is no buffer setting for the DVD plugin atm.
Don't use PMs for support questions.

Conclusion

I never was able to resolve this. I has concluded that it was an issue with my box. To verify this I install DVD support for Xine, and it does the same thing, although to a much milder degree.

I assume this is related to my Video driver. There is not actually a Linux video driver for my card(ATI 7000). I am using the driver for the ATI 7500.

Make sure your DVD drive has DMA transfers enabled (with hdparm).

That did it!!!

hdparm -d1 /dev/dvd

BEFORE :
Timing buffer-cache reads: 1444 MB in 2.00 seconds = 722.00 MB/sec
Timing buffered disk reads: 10 MB in 3.13 seconds = 3.20 MB/sec

AFTER :
Timing buffer-cache reads: 1456 MB in 2.00 seconds = 727.64 MB/sec
Timing buffered disk reads: 12 MB in 3.50 seconds = 3.43 MB/sec
