Hi,
I know that I won't be able to watch any programs with emperoartv, since all are coded in mpeg4, but anyway, I wanted to try. Unfortunately, event after replacing usb drivers with those that come with emperoar, my system traps when I start scanning channels, on the tv tuner driver.
I attempted to connect to different USB port, but no help. My system is ACP1.
ps. the tuner works fine on other machine with windows.

Hi,
are you sure that it's a MSI DigiVox mini II 3.0 ? Also, which trap
number at which CS:EIP ? I'm aware of a trap that might happen
with some sticks (already fixed here), however it should not affect
the model you mention...
BTW, please start TRACEFMT.EXE (after device attached) and
search for event Major 245 Minor 7. It should look like this:
Event [10] Major [245/0x00f5] Minor [7/0x0007] PID [1/0x0001] Length [26] Time [17:13:21.10]
Data [+0000 50 34 18 35 00 00 00 01-00 00 0A 00 64 35 B8 38 P4.5........d5.8 ]
Data [+0010 38 C0 9C 02 08 00 00 00-CC 10 8......... ]
I'm interested in the second line (starting with Data [+0010]).

This is the tuner I mentioned, at least according to what's written on it  THe trap is in AF9015, TRAP0000, CS:EIP=3df0:00004a7d Currently I am not able to retrieve trace data - I haven't use the utility before and there seems to be no trace file in the system and "trace on" does not work, for there is no file specified... I have to find out how to run this. |

Hmm, it's exactly the trap I was referring to. However, it happens only with sticks that use a MicroTune MT2060 and the MSI should be equipped with a Philips TDA18271... (At least mine here is). Anyway, please try this driver: http://telefon.s-t.de/rudi/af9015_test.zipIN order to get the trace stuff working be sure to have the line: TRACEBUF=127 in your CONFIG.SYS |

With the new driver I was able to detect channels without a crash. Ofcourse, no picture or sound, due to mpeg4 encoding.
Btw. with old driver the tracebuf line is:
Data [+0010 38 C0 82 02 08 00 C4 04-1D 8D 8......... ]
I was thinking... would it be possible to somehow store tv input with emperoar even though it is in mpeg4 and play/convert it with external software?

Obviously your stick does contain an MT2060. I was not aware of the fact, that MSI manufactured
these devices with different tuner chips. But who knows what was cheap at the moment of production...
Regarding your other question: I do have a command line tool that will dump the raw transport
stream (all programs on a given frequency) out to disk. However I don't think it's of much help...

stream (all programs on a given frequency) out to disk. However I don't think it's of much help... Could you provide me with this tool? A quick research with google showed that there are some (non-OS/2) tools that do the conversion of transport stream to avi/mpeg/etc. [/quote] |

Well, it's not that bad - I can play the transport stream with mplayer on OS/2. I haven't been able yet to get smooth video (although CPU is not utilized fully) and sound synchronized with video, but I'm trying it for 5 minutes only and I guess it's just settings tuning.
And now vision of a future - one could stream the script/emperoar output into an external player, thus giving a live TV, or instant saving of just only one channel...

To be honest, I don't really wan't (and support) a "hackish" interface with ETV. Currently the application is tightly tied to our own MPEG2 decoder, which I wrote back in 2000. The only chance to get H.264 to work is to modularize things so that open source codecs could be used. At the moment I cannot tell, if that is ever going to happen... |

Hi,
find a new version of the program attached. It accepts "-" as file name, which
means that the data stream will be sent to stdout. All textual messages go
to stderr, however it might still ask for a keypress in case of no signal.
