[mythtv] Playback Symptoms, Need Advice

[John Freer]

Hey all: 

Need some advice, not sure if all the symptoms are related or not: 

HW Background: 

XP2200, asus nforce2 MB, GF4 MX440/7167 Driver, RHFC3/KDE, 2.6.10 
atrpms kernel. 

Setup Background: 

-XvMC: Not Used but compiled in, but same symptoms with/without. 
-Lirc: Compiled in and used 
-DVB: Not used, not compiled in 
-Deinterlace: Not used, but same symptoms with/without. 
-1x PVR-250 -> MPEG2, 2x bt878 -> MPEG4: same results with both 
compressed filetypes 
-Same symptoms with ATRPMS mythtv-suite and with mythtv CVS from last

night. 

Symptoms: 

1. When I skip forward, the playback hangs for 1-2 seconds and 
pixellates badly before continuing playback. 

2. When any of the on screen display windows come up on the screen, 
they flicker badly when they are fading away (ie: show title bar, 
position indicator, etc) 

3. Occasionally (1 out of 3 times or so) the playback indicator will 
say something like: (0:05 of 250:00:00) even though it is an hour 
show. When I skip around a bit this goes away. 

4. Commercial flagging is not working correctly. I see that the 
mythcommflag thread fires up and is working (taking like 25% 
processor time), but I haven't yet found a recording that has the 
flagging performed on it. (when I hit skip, it says "Not Flagged") 

5. When I try to jump forward, playback hangs for ~20 seconds, then 
finally goes to the right position, pixellates for 5 seconds, then 
plays back. 


I used 0.16 with XvMC compiled in with a lot of success and none of 
these issues. How can I diagnose these problems? 

Thanks, 
John.
