Bug 52427

Summary:	DVD replay under MSI "655 MAX" mobo interrupted
Product:	Base System	Reporter:	J.D. <jimd_NOSPAM>
Component:	i386	Assignee:	Remko Lodder <remko>
Status:	Closed FIXED
Severity:	Affects Only Me	CC:	jimd
Priority:	Normal
Version:	4.8-STABLE
Hardware:	Any
OS:	Any

Description J.D. 2003-05-19 14:00:21 UTC

	Playing DVD under this environment results in video and audio blurs
	and skips almost in synchronization with the IDE controller activity
	LED. No amount of ATA DMA on/off settings or BIOS changes (HT on/off,
	APIC on/off) appear to make an difference. Note that setting ATA
	DMA "on" causes system lock up with 'BIG READ' errors.

	Using the exact same CD/DVD and HDD's (minus one extra LVD SCSI) on
	an MSI MS-6533XG motherboard (SiS 651/962 chipsets; onboard AC97:
	RealTek ALC650) with the exact same OS and software, but with a
	2.8GHz (non-HT) P4, does not exhibit any such problem with 
	DVD playback.

	Mplayer has no audio or video playback problems on the "655 Max".
	Playing audio CD's does not result in any playback problem.
	Xmms playback has no problems on the "655 Max".


	I have not yet tried the same under FBSD-5.1-BETA, on the same
	machine, as I have not installed all of the requisite S/W yet.

How-To-Repeat: 	Play any DVD

Comment 1 J.D. 2003-05-31 16:56:51 UTC

DVD playback audio via ogle, et al, under 5.1-BETA2 has no more skips, 
but the video playback still does. The video skips still seem to 
correlate with IDE/CDROM reads (IDE activity LED).

Using gmplayer (mplayer-gtk-esound-0.90.0.110_2) has reduced the video
skips dramatically, virtually eliminating them. Options enabled with
gmplayer (which have no equivalent with ogle or Goggles):

1) Video driver chosen: X11 (XImage/Shm)
	- enable double buffering
	- enable direct rendering

2) Misc
	- Enable postprocessing (auto quality = 0)
	- Cache on (size = 8192)
	- AutoSync on (value = 30)


The biggest changes in video synchronization were achieved with:

a) enabling double buffering
b) enabling cache=8192

Now there are only small "blips" which may be due to "missing frames" in
original video recording or mpeg generation, but they are usually not
noticable (they don't appear to "drag" the video motion or cause it to
"jump").

The IDE activity LED is now "furious with action" (ie; blinking very
rapidly), rather than emulating a slow heartbeat.

The video output quality appears to be slightly more grainy than that
shown by ogle/Goggles, but is acceptable. There may be more tunables
that will assist this, but I haven't tried everything yet. All three
programs (gmplayer, ogle, Goggles) exhibit slightly grainy/fluid
backgrounds, but gmplayer's is somewhat more noticable.


Note: this testing was done under FreeBSD 5.1-RC1.

So it seems that a lot of things happend in the past time after 
your report and that you almost elimated the problem by using 
a different player.  I am still curious however to see whether 
the current problem is still there in more recent versions of 
FreeBSD, can you tell that to me please?
