There is an error in what you added to BxDolAlbums.php which seems to be causing the file not found error for uploaded video files. When I run the cron manually it spits out this code every time for content. I also compared and see this is new function written for beta 7. This appears to be the root of the cuase for the File not Found Errors found when uploading videos. When I comment out the new if statement in BxDolCronVideo.php and the call to require BxDolAlbums.php my videos work perfectly.
UPDATE `sys_albums`, `sys_albums_objects` SET `ObjCount` = `ObjCount` + 1 WHERE `sys_albums`.`ID`=`sys_albums_objects`.`id_album` AND `sys_albums_objects`.`id_object`=17' AND `sys_albums`.`Type`='bx_videos'
Mysql error:
Found error in the file '[removed absolute path]/inc/classes/BxDolAlbums.php' at line 519.
Called 'res' function with erroneous argument #0.
If you want the bug backtrack letme know. Its a 1000 lines long and I dont' want to post it here.
