I recently set up gbpcr with comcast, using a dvico qam card on the pc, schedules direct for epg, and mvpmcx2 on a A110 via network browse. Works great for the most part, except I have this recurring problem. When witching channels on live tv via the arrow keys, I get a second or two of the new channel, then the screen goes black, and after several seconds I get thrown back to the tv guide. Live tv works great if I don't try to switch channels.
Any idea what's wrong?
If you compressed and upload your log files, I will have a look. I'm not optimistic, for now I think this is something that sub probably has to deal with, but since he already has improved digital stream capture significantly over the last year. I think it is just a matter of time.

Here are the logs. A couple of channel switches were actually successful, and I got the black screen and thrown back to the guide on the third change
Yes this is one of the problem scenarios that I suspect is a problem. If you noticed the last log sequence, the file stops growing{

So does that mean gbpvr stops appending the data stream to the file?
Once the NMT starts streaming it is important that GBPVR continuously provide data otherwise it thinks it reaches an end of file. I don't know what this log means but is one of the things I note when livetv stops on a channel change.
Martin
Thanks for your patience with my questions. If this is a known problem with gbpvr and digital sources, do you have any idea when a fix will be available?
On an unrelated note, I'm curious how you have written the nmt "mono" replacement. I thought the sigma libraries that interface with the actual video chip are not freely available?
My suggestion is to try in the next version when it comes out and bump sub if it still a problem.
As for the libraries, the sigma libraries like mono are closed source. I donated my time to Syabas to create a closed source library that I call instead of mono.
Martin
Thanks for the explanation. Is this Syabas library you created available for download somewhere (I mean the .a binary and the header files)?
Hopefully a .so will be available this fall but I'm waiting to see what Syabas does with the firmware after the C-200 comes out.
Note that the library is not a player, it will need a UI and a control module to make it do anything. This is a a lot of work too and since it can only do mpeg files it probably isn't going to attract a lot of developers.
