BTV4 with MediaMVP?

[bobbo]

I just bought a MediaMVP last month, and LiveTV with BTV v3.7.4 just started working this week (see MVPBTV v2.5, http://sourceforge.net/forum/forum.p...orum_id=369791).

Anybody tried MVPBTV with BTV4 yet? My setup is working well, and if it ain't broke...

I was wondering the same thing myself.

I can say everything works OK except I can't tell about LIVETV. The author said this weekend or early next week they will have a version that is fully compatible with BTV4 except for HD stuff. The MVP will never display HD, it does not have the hardware to do it.



Thanks
Mike

I just tried it and it gets to loading Live TV then gives a buffer error message. I'll wait a couple of days on the fix and try it again later. Like the new color on it though.

According to this message in the MVPBTV forum:

http://sourceforge.net/forum/message.php?msg_id=3450640

All you need is the "Guide.html" file updated to get MVPBTV to work with BTV4. You can get the new file from the CVS here:

http://cvs.sourceforge.net/viewcvs.py/mvpbtv/BTV35/

So I'm going to download BTV4 and give it a go. I'll report back my results, I'm really hoping that LiveTV to the MediaMVP stays functional!

I tried that new guide.html about a week ago and it worked fine for me to watch liveTV in BTV. Only problem is that it only works once and then I have to power cycle the MVP. If I try to use LiveTV after it has worked once it just says that it is preparing livetv and then that message disappears and nothing happens. I do get control back of the MVP and everything else works in it fine except liveTV which again requires me to power cycle the MVP for it to work again.

Yeah, I had problems when I tried the file from the CVS to. But then I tried another trick: I took the "playLiveTV" function from the new Guide.html and pasted it into my old file, and lo-and-behold it works! I've attached the file.

I've had it running for 24hrs now, no hickups or reboots at all. You still go back to the guide to select the LiveTV channel you want to watch (no up/down channel function), but that's a feature request not a bug.

One more tip, nothing to do with BTV4, but check out this thread on MVP network tweaks. It made my unit go from extremely sluggish to as good as my BTVLink machine!

Almost forgot to mention, with BTV4 you get a new license key, so don't forget to update your "user_config.js" file or it won't work.

bobbo - What tweaks did you actually use? I clicked on the links you provided and only ended up chasing my own tail. The post above the one you linked to has two zip files that are corrupt.

Thanks.

I replaced the original guide.htm file in C:\Program Files\Hauppauge Media MVP with the new one you attached and Live TV now works great on the MVP with BTV4.

Thanks again....

For the network tweaks, you have to read through the whole thread (all six pages) and pull tips from individual posts. I've copied-n-pasted a bunch of them below, hope this helps. Usual disclaimers apply (if you mess with the registry, your computer will explode).

1. Set your NIC to 100 Full Duplex not auto sense.

2. enable NIC onboard processor:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters]
"DisableTaskOffload"=dword:00000000

3. Lanmanworkstation default buffers: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\lanmanworkstation\parameters]
"MaxCmds"=dword:00000064
"MaxCollectionCount"=dword:ffff
"MaxThreads"=dword:00000064
"SizReqBuf"=dword:4000

4. TCP Windows Size, TTL:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters]
"GlobalMaxTcpWindowSize"=dword:000a00b0
"TcpWindowSize"=dword:000a00b0
"DefaultTTL"=dword:00000040

5. DNS Cache:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Dnscache\Parameters]
"CacheHashTableSize"=dword:00000180
"CacheHashTableBucketSize"=dword:00000001
"MaxCacheEntryTtlLimit"=dword:00000040
"MaxSOACacheEntryTtlLimit"=dword:0000012d
"NegativeCacheTime"=dword:00000000

6. Internet Server Settings:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Internet Settings]
"MaxConnectionsPerServer"=dword:00000032
"MaxConnectionsPer1_0Server"=dword:00000032

7. Set your Mozilla and MS IE browsers cache no higher than 70MB (delete old cache first!)

8. Tweak MTU settings
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters]
"Tcp1323Opts"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:000a00b0
"TcpWindowSize"=dword:000a00b0
"EnablePMTUDiscovery"=dword:00000001
"SackOpts"=dword:00000001

9. XP Pro SP1 or SP2, disable QOS without removing it:
a. click on start
b. click on run

d. click on administrative templates
e. click on network
f. click on Qos Packet Scheduler
g. on the right plane double click on Limited revservable bandwidth

10. Disable unused services (start>run>"services.msc"):
Windows XP Firewall
SSDP *
Wireless (only if your not running anything wireless)
Secondary Logon
Net Logon (unless your on a domain, workgroups disabled)
Remote Registry
Help and Support (big memory hog, but it can be disabled)
Error Reporting (another big one, but it can be disabled)
IPSEC Service
NetMeeting Remote Desktop
Task Scheduler (if you're not using this feature disable it)
Telenet (if you're not using a CISCO router disable this)
Telephony (if you don't have a dial-up modem disable this)
Index Service (this can really pull down your system disable it)

13. RESET YOUR MODEM REGULARLY (Cable and DSL):
Another thing to do about once a week if you modem is on 24/7 is to power cycle your modem, just completely disconnect power from it for atleast 15 seconds and then power it back on.
