[MarcRandolph <mrand@xxxxxxxxx>]

Howdy, and thank you for helping to improve Mythbuntu by opening this ticket.  While I don't have direct experience with this piece of hardware, I'm a bit puzzled by your problem because looking through mythtv mailing list archives and such, it seems to be a widely used card.
Perhaps you could try a different firmware load (maybe there is a problem between the driver and default firmware that is loaded)?   You might look over  http://www.mythtv.org/wiki/Hauppauge_PVR-500

Also, if you haven't already, you study closely the output of: dmesg |
egrep -i '(ivtv|tveeprom|tuner)', and please post a copy to this bug.

I might try reconfiguring (maybe even going so far as to delete the
card/tuner and re-add) the device via mythtv-setup.

Just for reference, here are the related entries from backend log file:

Status in “mythtv” package in Ubuntu: New

Bug description:
Binary package hint: mythtv

I'm running MythBuntu 8.10 without a problem.
Upgrading to 9.04 or 9.10 causes my livetv to be very distorted and basically unviewable.

Today I attempted a new 10.04 beta install to see if anything has changed. My problem persists.

What I find strange is that when viewing my /dev/videox directly using VLC, I can view the channel perfectly.
However, when I first try to view a channel with MythTV and then try to view it using VLC, I get identical problems on the channel.

On the other input on the same card, if I haven't used/tried that in mythtv yet, I can use VLC again without a problem.
The errors VLC gives (when first viewing the channel with mythtv and then VLC):
[0xb6b01ae0] main input error: ES_OUT_SET_(GROUP_)PCR  is called too late, increasing pts_delay to 816 ms

I would think this is not driver or kernel related, since playing TV directly from VLC works. Once I try mythtv, I can't play TV (decently) using any program from that point, untill a system reboot.
