Video drivers?
Hi,

have gotten a lot of crashes after I made the patch for DVB Channel change, I don't think the patch is the source of this, but I suspect that my video drivers are messing up.

My setup is a:
Shuttle X with nForce 2 (the old ver)
Athlon XP 1700+
256MB 'Low Bidder' Memory
No HD, booted over onboard lan chip.
Hauppauge Nexus-S with CI-CAM (Conax)

It is a clean RedHat 9 with CVS MythTV (always fresh).

Any input is helpful.

Kenneth.

I doubt it's the video drivers. More likely, you missed reinitializing
something when the video parameters changed.

Sometimes I get it 8-10 times in a row, but after reboots it seems to
settle?

This does not sound like something I did (?), as a sidenote, I know I there
is a lot missing in the patch, but it does not segfault when wiriting to one
of the buffers, but somewhere after blit to screen..

Probably because you're corrupting memory somewhere.

Like a (random) stray pointer or something?
Might be, but seriously, I doubt it, after my last reboot, about 1 1/2 hours
ago, the system has been rock solid, with several channel changes...I think
it goes beyond MythTV, and deeper into my system.

Re: Video drivers? [ In reply to ]
I do experience similar things since I do work with DVB.
My dvb drivers are the June pre3.
Since I've using dvb for many time with vdr and it was stable, I do suspect
it is related to the mythtv/libmyth/libdvbdev.
I have also more success tuning with dvbstream than tuning with mythtv and
it doesn't make sense...
While working on my current devs, I'm looking to findout the differences,
we'll catch it.
