#6456: DVD Playback stutters
-----------------------------------+----------------------------------------
Reporter: alan at eng.com | Owner: skamithi
Type: defect | Status: new
Priority: major | Milestone: unknown
Component: MythTV - DVD Playback | Version: 0.21-fixes
Severity: high | Mlocked: 0
-----------------------------------+----------------------------------------
Nearly all DVDs stutter when played with the internal player, and it is
especially bad with Animusic 2. The same DVDs play perfectly with Xine.
Also, ripping the DVD to an ISO and playing using the internal player in
MythVideo (across NFS) works perfectly.
Disabling Monitor DVD/CD improves the situation, but does not solve it.
Disabling deinterlacing etc. makes no difference.
The most common error message during the stuttering is
Video is XXXXXX frames behind audio (too slow), dropping frame to catch
up.
Increasing the playback speed to 1.1x or reducing to 0.9x eliminate the
stutter completely.
My DVD drive is a SATA drive, but switching to an IDE drive makes no
difference (DMA is shown as enabled in both cases)
I have had the problem for a long time (since 0.21, but not in 0.20-X),
but have not had chance to eliminate all issues until recently.
Attached is an old log file, captured while trying to debug this issue.
I am running Ubuntu 8.04.1 and Mythbuntu weekly builds of 0.21-fixes
(currently 20324).
Thanks
Alan
