Summary	05681: SDL-based: Most Laserdisc CHD games either do not boot or have other issues
Description	Specific to SDLMAME (Windows), the Laserdisc CHDs are not working as described below: cliffhgr, cobra, cobram3 - hangs immediately before loading firefox - second sky stage (choose 3000mi mission) the video screen freezes, but targets continue to show cubeqst - no coin - no video - seems to hang at "Cube Button for Instruction" screen mach3 - "Disc Error - Stay Put" error while entering initials on high score screen usvsthem seems to be the only image I was able to play without issue Update from Barnacle Ed: On SDLMAME64 0.154 running on Linux x64, I tested "cliffhgr", which does not hang, however it also does not work properly. Audio plays, but no video plays, either in the disc test or in attract/game mode. This is all I am able to test at the current time, but the problem extends beyond SDL on Windows.

Most of laserdisc games with such configuration changing speed constantly for example from 98% to 102%.

No.10955 NekoEd Senior Tester Aug 26, 2014, 23:36	Confirming video does display using -video soft in Linux SDLMAME.
