Post subject:  Online Streams crashes: 'No buttons for menu is.xml'
Howdy. Fresh LinHES install and Online Streams section worked. Online Streams is where Apple Trailers and MythStream live.

Then I upgraded to myth-vdpau (my computer simply won't play over-the-air without it), then Online Streams section broke. When I remove mythtv-vdpau and return to mythtv and stable nvidia, Online Streams is STILL broken leading me to believe the snafu is somewhere fixable in configuration and not a problem with myth-vdpau. Here's what happens:

When I go into Main > Media Library > Online Streams,
I get a screen blank except for the MythTV theme background with today's date. If I hit ENTER or ESC, mythfrontend is poof! and I'm back at the LinHES X desktop.

Here is entire log. (Note when I enter "Online Streams" section.)

(Again, after configuration changes, and even removing updates and returning to originals (via pacman) "Online Streams" section is still broken.)

For comparison, here is the entire log from a fresh r6...07 install, when "Online Streams" works.

Wow, well, I don't know what the problem was, but with no idea of what I'm doing, and brute force, I solved it with backtracking. (Replacing less than the three following items doesn't seem to do the trick for whatever reason -- gotta do all three). Anybody know what the "no buttons" error meant? Anyway...

So here's what I did:

- Fresh default install of r6...07.

- Using tar/gzip I made archives of the following files and directories:

/usr/share/mythtv/
/home/mythtv/.mythtv/
/usr/lib/mythtv/plugins/libmythstream.so

- Then using pacman updated linHES scripts, removed mythtv; installed myth-vdpau; removed nvidia; installed nvidia-beta (necessary for some reason, otherwise my X dies).

- Then I deleted the three items listed above (which also happens to delete "mythstream" dir which appears in both otherwise very differently configured locations. Maybe the existence of these two is a snafu in r6 or mythtv or mythtv-vdpau? Remember, restoring mythtv and nvidia did NOT restore Online Streams to working.)

- Then I restored these three files/directories from the archives made in step one.

For noobs like me, here was a successful sequence of events (with safety measures and shots in the dark included. I'm proud of myself :? ) -- enjoy!

hey there,

I have the same problem...

one night (shortly after installing R6), i discovered the joy of online streams, and apple trailers... it just worked on the defaults with R6 preview... i was impressed..

Then in the next few weeks, i did a pacman update, and i have the behaviour described below (no entries in the onlinestreams, crash frontend)...

Any ideas? Should i do another pacman update, and hope it be fixed?

BTW, I didnt do any vdpau installs, so i think you can focus on the regular default packages as the culprits?

Cheers,

Nathan

This is an irritating bug that has been around since the release of the R6 preview. It's been fixed for a while in the standard MythTV packages, but apparently not in mythtv-vdpau. The problem lies with the file /usr/share/mythtv/is.xml. By default, is.xml is a blank file. When you install extra packages like mythvodka, Miro player, etc., those packages add entries to is.xml as part of their installation. When you upgraded to mythtv-vdpau, is.xml was overwritten with that blank file again, and now the frontend is crashing when it tries to interpret a blank file as a menu.

If you look here, you will find the contents of the original is.xml which you can cut and paste into /usr/share/mythtv/is.xml, thus preventing the frontend crashing. There's also a bit of text you should add to the end of /usr/share/mythtv/media_settings.xml if you use MythVodka.

Thank you, Nickca! That is essential info! I actually posted a report way back but Jams closed it down with no info, saying myth-vdpau would not (and should not) be supported. :) Unfortunately I need it. Thank you for this!!
