Can No Longer Play DVD Isos

[DReaper]

Describe the bug
When playing a DVD .iso, it attempts to read it as a Blu-Ray, then fails to read. DVD playback has worked in older versions. I updated from 6.0.3.0, which worked. I am unsure if this broke in recent versions.

To Reproduce
Click and drag any DVD .iso over to the player

Expected behavior
In previous versions, a pop-up would ask whether it was a DVD or Blu-Ray. Selecting DVD would playback with no issues. This feature was implemented in 5.4.8.4 Beta

Additional context
No issues with Blu-Ray playback, only DVDs.

To note, this issue is happening on the latest 7.1.1.0 version.

If I mount the iso file outside of mpv.net and open it through Open DVD/Blu-Ray Drive/Folder, it will playback fine. The issue is only if you attempt to direct play a DVD iso.

Looks like DVD iso handling was removed in newest version for some reason:

mpv.net/src/MpvNet/Player.cs

Lines 491 to 497 in 3f52c12

	public void LoadBluRayISO(string path)
	{
	Command("stop");
	Thread.Sleep(500);
	SetPropertyString("bluray-device", path);
	LoadFiles(new[] { @"bd://" }, false, false);
	}

older mpv.net handled this differently:

mpv.net/src/Misc/Player.cs

Lines 1246 to 1271 in dbf1a32

	public void LoadISO(string path)
	{
	long gb = new FileInfo(path).Length / 1024 / 1024 / 1024;
	if (gb < 10)
	{
	System.Windows.MessageBoxResult result =
	Msg.ShowQuestion("Click Yes for Blu-ray and No for DVD.",
	System.Windows.MessageBoxButton.YesNoCancel);
	switch (result)
	{
	case System.Windows.MessageBoxResult.Yes:
	Command("stop");
	Thread.Sleep(500);
	SetPropertyString("bluray-device", path);
	LoadFiles(new[] { @"bd://" }, false, false);
	break;
	case System.Windows.MessageBoxResult.No:
	Command("stop");
	Thread.Sleep(500);
	SetPropertyString("dvd-device", path);
	LoadFiles(new[] { @"dvd://" }, false, false);
	break;
	}
	}

And unfortunately you can't use a lua script to handle this:

local function check_iso()
    local path = mp.get_property("path")
    local extension = string.match(path, "%.([^%.]+)$")
    local extension = extension and extension:lower()

    if extension == "iso" then
        mp.register_event("end-file", function(event)
            if event.reason == "error" then
                if mp.get_property("bluray-device") == path then
                    mp.set_property("bluray-device", "")
                    mp.set_property("dvd-device", path)
                    mp.commandv("loadfile", "dvd://")
                end
            elseif mp.get_property("dvd-device") == path then
                mp.set_property("dvd-device", "")
            end
            mp.unregister_event("end-file")
        end)

        mp.set_property("bluray-device", path)
        mp.commandv("loadfile", "bd://")
        iso_loaded=true
    end
end

mp.register_event("file-loaded", check_iso)

mp.register_event("end-file", function(event)
    if mp.get_property_bool("idle-active") then
        if iso_loaded and (event.reason == "eof" or event.reason == "stop") then
             mp.set_property("bluray-device", "")
             mp.set_property("dvd-device", "")
             iso_loaded=false
        end
    end
end)

because mpv.net hijacks the iso loading instantly and the script never executes.
