Rittberg Posted October 23, 2006 Share Posted October 23, 2006 (edited) Hi, Due to the fact that I am located outside Europe and even using large dishes, I face that reception quality is changing during the day time. During the watching of HiDef H264 channels by DVBViewer 3.5.0.41, at the moment that the signal quality drops (less than 35%) the HTPC simply crash and reboots again. Is there a way in such case to let DVBViewer application to close and to eliminate the HTPC crashing ? Thanks. Edited October 23, 2006 by Rittberg Quote Link to comment
Griga Posted October 23, 2006 Share Posted October 23, 2006 the HTPC simply crash and reboots again. In most cases rebooting is caused by driver issues. An application can hardly let the whole system crash under WinXP. Try to find out which component causes the reboot. Disable the automatic reboot in case of critical errors (somewhere under My Computer -> Properties). After that, the "Blue Screen of Death" will tell you what happened. Quote Link to comment

Griga Posted October 24, 2006 Share Posted October 24, 2006 Sorry, no. Mostly the BSOD displays the dll/sys or whatever file that caused the crash. That would be helpful to know. Quote Link to comment
Rittberg Posted October 25, 2006 Author Share Posted October 25, 2006 I am not able to supply a BSOD display even I disable the "automatic reboot in case of critical errors" due to the fact that most of the time the screen become black and I can hear an annoying noise but no BSOD screen , I can stop this only by pressing "reset". I find that even with a strong signal but with a channel broadcasting in a none 1920*1080 resolution as LUXE HD @ 1280*1080 (according to DVBViewer) the HTPC crash too. I have checked the memories with "windows memory diagnostics" and they are OK. Thanks for your input. Quote Link to comment
Griga Posted October 25, 2006 Share Posted October 25, 2006 due to the fact that most of the time the screen become black and I can hear an annoying noise but no BSOD screen Suggests that the graphics card driver or even the graphics card itself causes the crash, maybe due to corrupted video data in conjunction with HW acceleration (enabled for H.264?). but with a channel broadcasting in a none 1920*1080 resolution as LUXE HD @ 1280*1080 (according to DVBViewer) the HTPC crash too. Make sure that Options -> DirectX -> Video Format Detection is ticked! Most H.264 decoders (in contrast to MPEG2 decoders) are not able to detect the video resolution correctly, so DVBViewer has to do it for them. Otherwise all kinds of nasty things may happen...

Rittberg Posted October 25, 2006 Author Share Posted October 25, 2006 Suggests that the graphics card driver or even the graphics card itself causes the crash, maybe due to corrupted video data in conjunction with HW acceleration (enabled for H.264?). It seems that you are right, When disabling the H.264 HW acceleration in PDVD or using CoreAVC I can't remember a PC crash, But the picture quality is not fluent as with H.264 HW acceleration "on" and this is not a question of CPU (I am using the E6700 + Nvidia 7900). So, in order to solve the problem we have to wait for what : 1. PDVD - better SW ? 2. Nvidia - better driver ? 3. TT S - 3200 - better driver ? BTW - Video Format Detection is ticked. Thanks again.

Griga Posted October 25, 2006 Share Posted October 25, 2006 I'd say, 1. and/or 2. Quite unlikely that the TT 3200 driver is involved. Quote Link to comment
Rittberg Posted October 26, 2006 Author Share Posted October 26, 2006 I attached a compressed "MINI.DUMP" file with the reports from the last days, Can this help to understand better the crashes ? Thanks. Mini101406_04.rar Quote Link to comment
Rittberg Posted October 27, 2006 Author Share Posted October 27, 2006 Update: with Griga's direction I find that PDVD 7 HW acceleration need perfect video data , if not my HTPC is keeping crashing all the time, This is not the case when using PDVD 7 with HW acceleration - disabled or with CoreAVC. I upload a H.264 corrupted video file where you can see/check your system. Even the playback of this file using PDVD 7 HW acceleration crashes the HTPC, but playback of the same file with PDVD 7 (HW acceleration - disabled) or with CoreAVC is OK. The question is how that problem can be solved or how to tell PDVD & Nvidia to investigate that issue. In case you are facing DL problems use FireFox . the file link : http://s1.upload.sc/request/2d55387da33a44...b5d65eb77/owner Thanks for your input. Quote Link to comment
Rittberg Posted November 3, 2006 Author Share Posted November 3, 2006 Installed today the new Nvidia Forceware 93.71, and no change - corrupted video data & H.264 HW acceleration "on" = PC crash Quote Link to comment
