Description
Playing two videos in a row that use VDPAU with MythVideo? results in the UI hanging and errors in the log file.
Reproducing this is fairly easy. I start up Myth, go to MythVideo?, and pick a DVD to play. This first one plays fine. Then, exit out of that DVD and pick a different one. The "Please wait" screen comes up, and stays there forever.
Looking in the log shows these errors :
2009-10-17 21:26:34.341 AFD: Opened codec 0xbdeb690, id(MPEG2VIDEO) type(Video) 2009-10-17 21:26:34.341 NVP(2): Disabling Audio, params(-1,-1,-1) 2009-10-17 21:26:34.430 VidOutVDPAU Error: Failed to initialise VDPAU 2009-10-17 21:26:34.445 VideoOutput?, Error: Not compiled with any useable video output method. 2009-10-17 21:26:34.445 NVP(2), Error: Couldn't create VideoOutput? instance.

If I play a DVD, go out and view a recorded show, and then pick a different DVD, it seems to work fine. Which makes me suspect it may be an issue with how VDPAU is inited and deinited. FWIW - I saw similar problems with the 0.21-fixes version with the VDPAU patch, except that was a problem throughout the entire system.
The machine that I am using this on is an Acer Aspire Revo. Specs are here :

Per the log:
2009-10-18 09:47:40.191 VDPAU Error: Error at util-vdpau.cpp:871 (#23, The system does not have enough resources to complete the requested operation at this time.)
Can you try increasing the shared ram alotted to the GPU? It appears you may have it set too low (128 or 156M, you likely need at least 512M).

The box defaults to 128M, but maxes out at 256M. I pushed it up to the 256M max, and I can play back DVDs properly now.
However, I would still suggest that there is a bug here. When an error happens in the decoding, the system shouldn't stop at the "Please Wait..." screen forever. It effectively renders the box useless until Myth is killed and restarted. Instead, I would suggest that some error be displayed so that the user has some indication of why the system failed.
That said, this is probably a low priority issue. ;)

At the moment the stated minimum for Myth VDPAU is 512 MB. That may change in the future, but for now anything less is on an "as-is" basis.
logs w/ -v playback, please.
