How to Convert .rm and .rmvb larger than 40Mb on AviSyth

[mcra3005]

To whom it may Concern,

I am converting .rm and .rmvb files via AviSynth to VirtualDub then to Tmpenc.
I have done acouple hundred no problem, but recently I have tried to open a
file which was larger than 40Mb I tried afew large ones, and got the same problem.

Saying DirectShowSource could not open file stream due to no be able to find the approiate filters, Maybe not the exact wording but pretty close.

Now I have installed Real Alternative, which means if I try to open a .Rm or Rmvb file by Windows media player it will use the realmedia dll's some how and play them, this does work for the files less than 40mb and ones greater than 40Mb, but when I make a file i.e. a .avs file
with one line DirectShowSource ( Filename , fps=25 , convert=true) something like this
I know the syntax I use in my script since I have used this for over 300 files. But when I
specfy a file name a .rm or .rmvb file which is more than 40Mb in size and double click on the .avs file to tes it it tries to Open a the Windows Media player but fails with the error mention. If I dont open it by the .avs file but directly click on the .rm file it works.
Which would indicate some bug with Avisyth to me, I have the 2.56 version, I tried the 2.57
but it didn't fix it so I went back to 2.56.

Any ideas how to fix this or what to look for.

Waiting for a reply....

maybe they are files with more than one video/audio stream.
check with surestream utility in this link
http://forum.doom9.org/showthread.php?s=&threadid=86264
and if needed extract to new file with single video and audio stream.
If above does not help, try creating grf files separately for video and audio with graphedit and loading them via directshowsource.

Why rmvb-->AVISynth-->VDub-->TMPGEnc
and not
rmvb-->TMPGEnc
?

TMPGEnc should be able to read rmvb's via dshow directly.

To Celtic druid, I did orignal go .rmvb to TMPGEnc but I am converting Anime video which is blurry, I tried all the filters to unblur and sharpen, but I found Vdub kill the rest for results compared to the rest. So that is why I do it this way, tonight i am going to check if thes files have muliply streams or not as recommended by mgh, but i don't think I will do this graph edit tool since my XP box will have to install a .net plug in's etc, and it might mess up all my other apps. I will see what happens, any other suggestions welcome.

Regards.

Graphedit doesn't require .Net.

I finally got around to look at the problem agin Kids and all. Any way I tried the straem software to see if two stvideo streams were there they were not. So I tried to open up the files again to reverify the problem, but they all work now. So yes it is possible to open up rm, and rmvb files via AVIsyth so far I tested up to 150Mb sucessfully. Now the only thing I did between theproblem, like I said I tried to install AviSyth the latest version but did not reboot my p.c., it did show it was the correct version so I uninstalled and reinsatlled my version same problem, but I didn't reboot. So all I can think the reinstall fixed up some dlls and registrys on my XP but need a reboot to come in affect. Anyway thanks for everyones assistance.

And if anyone has the same problem re-install AVIsyth and rebbot their box.

Regards.
