hi there.

i have been setting up my system to capture my basic cable using hvr-950q

so far i have gotten the backend set up using schedules direct and vl4 driver. everything looks ok.

when i enter livetv on xbmc (frodo) everything works. right down to connecting to the channel. i get a buffer but when it starts playing there is just a blank screen.

i can see and hear tv in tvtime fine.

i have installed the hvr-950q firmware in /lib/firmware but i noticed i had to reinstall it there after a recent restart. im not sure if this means anything or not as i still have the same problem in xbmc.

here is a screenshot

i have debugging enabled but the path shown on the screenshot doesnt seem to be there. there is however this soooo i am assuming this is the correct log file

Take your log and put it on pastebin.

Diagnosis step 1. Does mythfrontend work?

Thnaks for your reply.

No mythTV front end is not working.
I select "watch TV" and it goes to the start screen ( the old movie target thnig) and with in about 2 seconds kicks me out and back to the main menu.

I have installed xawtv so I could see the output while I was trying to initialize viewing.
here is the output sorry I can't seem to see were to find pastebin , I found a website but I can't input the ifram or java script to the post. It just shows the raw link code. feel free to point me in the right direction )

Where in this day and age are you getting analogue cable?

Possibly xawtv is not working because mythtbackend has the tuner locked?

[Nieboy]

thanks for your help.

I narrowed it down to a problem with the client I was using.

I reconfigured mysql then changed the myth plugin in xbmc to use the actual ip address of the machine....bam...it worked! but my remote machine upstairs still would't connect. I am using a PIVOS with linux intead of android so i figured maybe it had some sort of issue.
i switched it out to my HTPC that I was originally using anyways and BAM! again...it works like a charm. thanks for your help.


sorry to hijack y own thread but althought it is working i now have another slightly annoying problem.

there is a signifigant pixelization and audio spikehappening.i have boosted the signal justencase figuring it ws a good ide anyways, but no improvement.

i opened mythtv front end and everythhing i great in there no pixelization or audio spikes.

i have also enabled frame sync in xbmc playback as suggested somewhere in google . but no improvement

any ideas were to go from here? or is it a known problem with the plugin?

I suspect you have reception problems, which creates errors in the saved mpeg file.

Different players will react in different ways to the file errors.

If you have access to mythfrontend and it works better, just use it!
