I've been looking through the forums and might have missed what I need to know or something but I'm having a couple problems that I would really appreciate help with:
(btw I'm using knoppmyth R4V5, PVR-250, Gforce3 w/ SVIDEO TV-Out and an IR blaster to control a digital cable box)

1. The frontend will freeze up sporadically when I'm watching live TV (not recording or watching pre-recorded, and not about to start recording). I have a 8 gig space on the HDD that is used to cache live tv and I've folowed the hint of someone to decrease the setting in mythtv to less than the full amount (I set it to 7 gig). But this didn't seem to help any.

2. Freezups seems to happen after that translucent popup (that says it is asking if I want to watch it or stop recording it, yada yada) times out and starts the recording process. I know that the option of disabling the recording is not actually working with this version of mythtv(.61) but it freezes up when it let it time out and start recording. Is there anyway to disable that popup?

I'm wondering if it's a mythtv bug, HDD problem, video driver/module problem, or something else.

Any advice really be would appreciated.

You didn't do a very good search. It's a well known problem with MythTV 0.16, it is supposed to be fixed in 0.17.

thanks for the info, but things have gone from bad to worse.

as of yesterday the front end is losing connection to the backend, the image on the TV is starting to flicker off and on, and the tv gets little yellow blotches apearing and reapearing (visable even on the white BIOS text when the computer is booting up)

I think I may have a vid card problem, main board problem or some kind of heating problem.
(

If anyone has experienced the same, please let me know.

Well.. it doesn't have anything to do with heating as I left it turned off all night and when turning it back on it still had the yellowish text on portions of the screen.

I'm going to try using a diffent video card when I can find some one to borrow one from.

Anyone have any other suggestions?

My problem has been resolved.
I thought I would post it incase it can help someone.

I should have mentioned that on the last day before I turned off my mythtv box to start troubleshooting the hardware, it crashed 26 times that day.

I ended up replacing my Geforce3 with an MSI MX4000 (if I recall correctly), and the problem was solved. I think my G3 must have packed it in or the fan may have died and it over heated, or something. The new MSI only has a heatsink so I feel better about that.

It's been running without a frontend crash for about 5 days now.

kudos to you.

The fan on my GeForce2 MX 400 failed a while back and it was a few weeks before I noticed, and a few weeks after that before I fixed it. It was getting pretty noisy before it failed and it was nice and quiet afterwards It seemed a bit hot to the touch when it was running, but I dont think I got any instability as a result. I think I was hoping that it would fail to force my hand into getting something better.

Cool. Glad yours is still working. I think the cpu/gpu speed (or bus speed) is slower on the MX versions of the Geforce cards. That might be why yours kept trucking.
