Post subject:  TV402U Mostly Not Working
I have been trying to get my Plextor TV402U working with KnoppMyth R5A26.
I have had the same problem with R5A16 so I am not sure how much the release has to do with this. Anyways, I can not get the gadget to work in any consistant manner. If I do get it to work, it refuses to work after a reboot. By work I mean live TV and record. Live TV seems to work more often but I have gotten record to work only once. The following log excerpts are typical. This happen to be a reboot and starting a recording right away. There are some errors in the logs but I do not understand what they mean or if they are even relevant.

Code:

I am running KnoppMyth on a Soyo SY-P4I845PE with 1 GB memory, a P4 3.06GHz 533 FSB. It is a hyperthreading cpu with the hyperthreading turned off per the Plextor instructions. I have a PVR-350 that works just fine. It is /dev/video0 while the Plextor is /dev/video1. Both are using the composite inputs from a set top box each. I am using a nVidia FX-5200 video card with the drivers installed by R5A26.

I have deleted and reinstalled my Plextor once already in Setup.

If I have left anything out, I apologize but my mind is really tired after fooling with this for hours. For all the googling I did, it did not seem to yield much. Help is appreciated.

Other than this R5A26 is a really nice release. If I did not have this Plextor, it would have been a breeze.

Try
Code:
update-rc.d -f mythtv-backend remove
update-rc.d mythtv-backend defaults 50
This should start the backend after hotplug. Please let me know if this works for you.

Thanks Cesman. In my initial test it worked. It will take me a while to trust it but it looks like there is hope.

I had actually tried this mod earlier but it didn't have any effect. I think the device was hung, maybe the whole usb subsytem, after making so many changes and warm reboots. This time it was a slow, calm, and measured approach. I've have worked with linux for quite a while, NFS, Samba servers, Apache, installs, etc., but I never had to deal with usb or video. I think it was a case of knowing just enough to get me in trouble.

:) In the next release, I've set the backend to start after hotplug.
