[mythtv-users] Re:X Freezes blank on 'watch tv'

[mark mckelvey]

I have been having the same problem with my dual 833Mhz PIII mythbox 
(Dell Precision 420, 256Mb RAMBUS, PVR-250, 108ck ivtv, atrpms install 
per Jarod, 6111 nvidia driver) .  Mythvideo playback was working fine.  
Last night I may have fixed it so that everything is working, or maybe 
not of course :)

I scanned these posts and didn't find any details of your cpu spec, but 
i suspect that my box may have been having problems 
scaling/deinterlacing under live-TV and playback of recordings.  When I 
changed to 800x600 resolution through the S-Video out on my PNY MX440 
card, everything started working.  So if you are using a ~1280x1024-ish 
resolution on old-ish hardware like I was, I suggest you try reducing 
the resolution and see what effect that might have on the problem.

I have no idea how the scaling and xv-overlay work, so I might be 
talking nonsense (especially seeing as how the problem seems to come 
and go as it pleases), but at least for me, at least for now, this 
fixed the problem.  I suspect that it may be related to cpu power 
because I have never seen the problem with my XP1700+ mythbox which is 
running the same software versions all around.  If you're running dual 
6GHz P4s or something, it's probably something else :)
