Hi,
thanks for the bug report - I've just commit a fix that should
stop the seg fault - revision 322.
PS: I couldn't bunzip2 your log file when I downloaded it - it
said the file was corrupt - but I managed to work out what was happening
from the stack trace

I've tried it. It does not crash any more, I get the error message SI_TuneIndex: invalid service index (-1); range is 0-0 I've tried with the TV, and what happens is that Sport -> Sport in video sends you to page 1001, the same as the News Multiscreen, which with redbutton I cannot access either. I will repost my log in the same location (http://xoomer.alice.it/enodetti/log/log.txt.bz2), just for reference. As a side, I can report that there has been an improvement with video: 1) the video and the audio are good 2) video ratio is wrong, 4:3 instead that 19:9 3) I still get a lot of warnings: [mp3 @ 0xb7dd4c20]incorrect frame size 4) if I may, I would suggest to disable the ability to resize the window, which gives a not too nice effect of part of the screen not updated (in case it is made bigger) On 8/20/07, Simon Kilvington <s.k...@er...> wrote: > thanks for the bug report - I've just commit a fix that should > stop the seg fault - revision 322. > > PS: I couldn't bunzip2 your log file when I downloaded it - it > said the file was corrupt - but I managed to work out what was happening > from the stack trace |

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, the reason you get the error is because you cannot change channel because you are reading your MHEG data from a local file rather than downloading it - ie you are doing: rb-browser services/4164/ if you have rb-download running on the same host, you can just do: rb-download 4164 & rb-browser and it will use rb-download to change channel - that should stop the error and let you see BBC News Multiscreen too.
